Required Parameters

Parameter	Type	Default	Description
slug / boundary	string	-	Location slug for fetching boundary and data (e.g., "austin", "dc", "westwood")
list	string	-	Alternative to slug. List slug that provides configuration from the Lists API

Note: Either slug (or boundary) or list should be provided:

• slug: Fetches boundary and places within that geographic area
• list: Fetches list configuration which may include an organization (boundary), search filters, and theme settings

When using list:

• If the list has an organization, its slug is used as the boundary
• If the list has no organization, places are fetched globally using the list's filters and the map centers on markers
• URL parameters override list configuration (e.g., ?list=foo&editorialCategory=bar uses bar instead of list's default)

---

Map Viewport

Parameter	Type	Default	Description
latitude / lat	number	From boundary	Initial map center latitude
longitude / lng	number	From boundary	Initial map center longitude
zoom	number	From boundary	Initial zoom level (0-22)
bearing	number	0	Map rotation in degrees (0-360)
pitch	number	0	Map tilt in degrees (0-85)
zoomMode	string	"fit-boundary"	Initial zoom behavior: "fit-boundary" (fit to boundary polygon), "fit-markers" (fit to all markers), or "custom" (use explicit lat/lng/zoom)

Zoom Mode Details

The zoomMode parameter controls how the map determines its initial viewport:

Value	Behavior
fit-boundary	Default. Fits the map to the boundary polygon returned by the API
fit-markers	Calculates bounds from all marker coordinates and fits the map to show all markers with padding
custom	Uses explicit latitude, longitude, and zoom parameters; ignores boundary/marker bounds

Example - Fit to markers with auto-refit:

/embed/map-grid?slug=austin&zoomMode=fit-markers&refitMarkersOnFilterChange=true

---

Map Display

Parameter	Type	Default	Description
mapStyle	string	Vibemap default	Mapbox style URL (e.g., "mapbox://styles/mapbox/streets-v12")
mapHeight	number/string	"100%"	Map container height (px or CSS value)
mobileMaxHeight	number	-	Max iframe height in px on mobile viewports (does not affect desktop)
mobileBreakpoint	number	768	Viewport width threshold for mobileMaxHeight (px)
showBoundary	boolean	true	Show boundary polygon on map
showMarkers	boolean	true	Show place/event markers
showMarkersOutOfBoundary	boolean	Auto	Master toggle: show OOB markers everywhere (auto-enabled with radius/strictFilter). Logged-in users can also toggle via the Filters → Advanced panel.
showMarkersOutOfBoundaryOnMap	boolean	(master)	Show OOB markers on the map; falls back to showMarkersOutOfBoundary

showHeat	boolean	true	Show heatmap layer
map3d	boolean	false	Legacy 3D mode (use terrain3d instead)

Mobile Height Cap: On some mobile devices, the default 90% viewport height calculation can make the map too tall (e.g., screen.availHeight doesn't account for browser chrome). Use mobileMaxHeight to set a pixel cap that only applies when the parent viewport is narrower than mobileBreakpoint (default 768px). Desktop is unaffected.

# Cap map height at 500px on mobile
/embed/map-grid?slug=austin&mobileMaxHeight=500

# Cap at 600px for viewports under 1024px
/embed/map-grid?slug=austin&mobileMaxHeight=600&mobileBreakpoint=1024

markerLabels	string	"hide"	Label display: "hide", "featured", "all"
maxImageMarkers	number	Theme default	Max number of image markers to show
maxIconMarkers	number	Theme default	Max number of icon markers to show

---

Location Dots

Shows small dots at every GeoJSON location regardless of clustering, marker limits, or other display restrictions. Useful for showing the full extent of data when markers are limited.

Parameter	Type	Default	Description
showDots	boolean	false	Enable dots at all GeoJSON locations
dotsColor	string	Theme accent	Dot fill color (hex, e.g., "9B59B6" or "#9B59B6")
dotsRadius	number	4	Dot radius in pixels
dotsOpacity	number	1	Dot opacity (0-1)
dotsStrokeColor	string	-	Optional stroke/outline color for dots

Example - Show Dots with Custom Styling

/embed/map-grid?slug=austin&showDots=true&dotsColor=4a90e2&dotsRadius=3&dotsOpacity=0.5

---

Parking Layer

Separates parking items into a dedicated map layer rendered below regular markers. Parking items are detected by category (slugs starting with parking, e.g., parking, parking-charging, parking-private). When disabled, parking items are treated like any other place.

Parameter	Type	Default	Description
showParkingLayer	boolean	false	Separate parking items into a dedicated layer below regular markers

Example - Show Parking Layer

/embed/map-grid?slug=austin&showParkingLayer=true

---

Clustering

Parameter	Type	Default	Description
shouldCluster	boolean	false	Enable marker clustering
clusterRadius	number	Theme default	Pixel radius for clustering (typically 35-80)
clusterMaxZoom	number	Theme default	Max zoom level for clustering (integer, typically 14-18)

---

Grouping (Co-located Markers)

Groups markers that are at the same location (e.g., multiple events at the same venue). When clicked, groups expand to show individual items using either "spider" mode (circular spread) or "list" mode (scrollable popup).

Parameter	Type	Default	Description
enableGrouping	boolean	true	Enable grouping of co-located markers
groupingTolerance	number	3	Distance in meters within which items are considered co-located
spiderModeMaxItems	number	8	Max items for "spider" expansion (circular spread); larger groups show a scrollable list instead

How Grouping Works

1. Detection: Items within groupingTolerance meters of each other are grouped together
2. Display: Groups show a purple marker with a count badge indicating the number of items
3. Expansion modes:
   • Spider mode (≤ spiderModeMaxItems): Items spread out in a circle around the centroid with connecting lines
   • List mode (> spiderModeMaxItems): A scrollable popup appears with all items listed
4. Collapse: Click the X button at the centroid (spider mode) or close the popup (list mode)

Grouping vs Clustering

Feature	Grouping	Clustering
Purpose	Items at the same address/venue	Visual decluttering of nearby markers
Tolerance	~3 meters (same building)	35-80 pixels (screen distance)
Expansion	Spider web or scrollable list	Zoom to cluster bounds
Color	Purple	Teal (places) or Red (events)
When	Always (co-located items exist)	When zoomed out

Both features can be enabled simultaneously - clustering happens at zoom-out levels, grouping handles co-located items at any zoom level.

---

Boundary

Display

Parameter	Type	Default	Description
boundaryFilter	string	-	Filter to specific polygon by name (for MultiPolygon boundaries)
showBoundarySelectorList	boolean	true	Show boundary selector dropdown for MultiPolygon boundaries

showHoverPopoverOnPolygon	boolean	theme	Enable the hover popover/tooltip on boundary + overlay polygons. Falls back to theme.map.showHoverPopoverOnPolygon (default false).

Styling

Parameter	Type	Default	Description
boundaryFillColor	string	-	Fill color (hex, e.g., "#ff0000" or "%23ff0000" URL-encoded)
boundaryFillOpacity	number	0	Fill opacity (0-1)

showVibeFilter	boolean	true	Show vibes filter
showCategoryFilter	boolean	Auto	Show categories filter (auto for places)
showTagFilter	boolean	true	Show tags filter
showSearchFilter	boolean	true	Show search input
showTopLevelFilters	boolean	true	Show filters at top level (vs inside map)

Filter Behavior

Parameter	Type	Default	Description
filterViewMode	string	"horizontal"	Filter layout: "horizontal" or "tabbed"
filterSelectionMode	string	"auto"	Selection mode: "single", "multiple", "auto"
filterBehavior	string	"trapped"	Navigation behavior when taxonomy filters are passed (see below)
multiSelectTaxonomies	array	[]	JSON array of taxonomy names that allow multi-select
taxonomySortOrder	string	"count"	Sort order per taxonomy (see below)

Taxonomy Sort Order (taxonomySortOrder)

Controls how filter chips are sorted within each taxonomy. Default is count (most items first).

Format: "taxonomy:order,taxonomy:order" — comma-separated key:value pairs

Values:

Value	Description
count	Default. Sort by item count (most items first), then alphabetically
alpha	Alphabetical sorting (theme order → color → A-Z)

Examples:

# All taxonomies alphabetical
taxonomySortOrder=vibes:alpha,categories:alpha,tags:alpha

# Categories by count, vibes alphabetical
taxonomySortOrder=categories:count,vibes:alpha

# Just change tags to alphabetical (others stay as count)
taxonomySortOrder=tags:alpha

Filter Behavior Values (filterBehavior)

Controls how users can navigate taxonomy hierarchies when a taxonomy filter is passed via URL with strictFilter=true.

Value	Description
trapped	Default. User is locked within the passed taxonomy. Only the passed category/vibe/tag and its children are shown. User cannot navigate to parent/sibling taxonomies.
selected	The passed filter is pre-selected, but user can deselect it to see parent-level filters. Allows escaping the passed taxonomy.
open	Current behavior - all taxonomies from returned items are shown, regardless of what was passed.

Important Notes:

• Only applies when strictFilter=true. Without strictFilter, the parameter is ignored and behavior defaults to open.
• If multiple taxonomy values are passed (e.g., ?categories=shop,food), behavior automatically switches to open.
• Applies to all taxonomy types: categories (hierarchical), vibes (flat), and tags (flat).

Taxonomy Labels

Customize the display names for taxonomy sections in the filters UI.

Parameter	Type	Default	Description
vibesLabel	string	"Vibes"	Custom display name for the Vibes taxonomy
categoriesLabel	string	"Categories"	Custom display name for the Categories taxonomy
tagsLabel	string	"Tags"	Custom display name for the Tags taxonomy

Examples:

# Rename "Vibes" to "Feel"
/embed/map-grid?slug=austin&vibesLabel=Feel

# Rename all taxonomies
/embed/map-grid?slug=austin&vibesLabel=Mood&categoriesLabel=Types&tagsLabel=Keywords

# Partial override (only change Vibes, others keep defaults)
/embed/map-grid?slug=austin&vibesLabel=Tags

Date Filters (Events)

Parameter	Type	Default	Description
showDateRangeSelector	boolean	true	Show date range selector (events only)
dateFilterOptions	array	["upcoming","today","weekend","next_week","month"]	Available date filter options

Date Boundary (Events)

Hard date limits that exclude events outside the range, regardless of user filter selections.

Parameter	Type	Default	Description
dateBoundaryStart	string	-	Events before this date are excluded. Accepts yyyy-MM-dd or relative offset.
dateBoundaryEnd	string	-	Events after this date are excluded. Accepts yyyy-MM-dd or relative offset.

Relative offset format: +Nd (days), +Nm (months), +Ny (years). Negative values work too (-7d = 7 days ago). The offset is computed fresh on each page load relative to the current date.

Examples:

# Only show events in the next 14 days
/embed/map-grid?slug=austin&type=events&dateBoundaryEnd=%2B14d

# Next 3 months of events
/embed/map-grid?slug=austin&type=events&dateBoundaryEnd=%2B3m

# Events between specific dates
/embed/map-grid?slug=austin&type=events&dateBoundaryStart=2026-06-01&dateBoundaryEnd=2026-09-01

# Events from today through end of year
/embed/map-grid?slug=austin&type=events&dateBoundaryStart=%2B0d&dateBoundaryEnd=%2B1y

Note: The + character must be URL-encoded as %2B in query strings.

Past Event Window

Controls how long after an event's end time it remains visible. Default keeps every event visible for 90 minutes after it ends, so events with identical start/end times don't disappear the instant they begin.

Parameter	Type	Default	Description
pastWindow	integer (minutes)	90	Minutes after end_date that an event remains eligible. 0 cuts at end. 1440 shows for 1 day. 10080 shows for a week. Overridden by pastCutoff if both are set.
pastCutoff	ISO 8601 datetime	–	Absolute floor — only events with end_date >= pastCutoff are shown, e.g. 2026-06-01T00:00:00. Site-local time. Overrides pastWindow when set.

Examples:

# Show events for 6 hours after they end
/embed/map-grid?slug=austin&type=events&pastWindow=360

# Show all events from the past week onward
/embed/map-grid?slug=austin&type=events&pastWindow=10080

# Show every event ending on/after June 1, 2026
/embed/map-grid?slug=austin&type=events&pastCutoff=2026-06-01T00:00:00

Updates Position Values: under-vibes, under-description, before-hours, before-links, after-links

Example - Show Offers Only:

/embed/map-grid?slug=austin&showUpdates=true&updatesFilterTypes=Offer&updatesDisplayMode=badge

---

Theme

Parameter	Type	Default	Description
theme / themeName	string	"default"	Theme slug for styling (e.g., "dark", "minimal")

Themes can provide defaults for many parameters above, reducing URL complexity.

---

Banner Ads

Parameter	Type	Default	Description
mobileAdPlacement	string	"above"	Where banner ads appear on mobile (see below)

Banner ads are configured per-theme (via the theme parameter) or per-block in WordPress. The mobileAdPlacement parameter controls where ads render on mobile viewports (< 768px). On desktop, ads always appear in the header alongside filter chips.

Value	Behavior
header	Ads stay inside the header on mobile (legacy behavior)
above	Default. Both ad slots render above the map/grid on mobile
below	Both ad slots render below the map/grid on mobile
split	Slot 1 renders above, Slot 2 renders below the map/grid on mobile

Mobile ads render outside the map container, so they do not affect the map height (e.g., a 700px map stays 700px; ads take additional space).

# Both ads above the map on mobile
/embed/map-grid?slug=austin&theme=lynnwood&mobileAdPlacement=above

# Split: one ad above, one below
/embed/map-grid?slug=austin&theme=lynnwood&mobileAdPlacement=split

# Keep ads in the header (desktop-like behavior on mobile)
/embed/map-grid?slug=austin&theme=lynnwood&mobileAdPlacement=header

---

Advanced

Parameter	Type	Default	Description
heatmap	boolean	true	Enable heatmap functionality
showExplore	boolean	true	Show explore features
showEvents	boolean	true	Show events on map
showPlaces	boolean	true	Show places on map

---

Admin Display Settings (logged-in users only)

The Advanced panel exposed in the Filters bar to logged-in users surfaces display toggles that change what appears in the embed:

• Show unapproved — drops is_approved=true from API queries
• Show closed places — drops is_closed=false (places only)
• Hide items without images
• Min completeness score
• Show items outside boundary (map-grid only — overrides the existing showMarkersOutOfBoundary cascade)

These are admin-only and intentionally have no URL surface. The toggles exist solely in the Advanced panel for logged-in users. User overrides are persisted per-embed-instance in localStorage. Cascade for resolution: user override (panel) > theme default > code default.

The persistence scope is keyed by a hash of themeName + type + listId + cityId + boundary + embedInstance. Two identically-configured iframes on the same host page share state by design; pass embedInstance=foo (URL param) to force separation.

Parameter	Type	Default	Description
embedInstance	string	-	Optional opaque suffix used to give two otherwise-identical embeds independent admin-override scopes.
hideNoImageItems	boolean	false	Pre-existing public param; logged-in users can also override via the panel.
showMarkersOutOfBoundary	boolean	(theme/auto)	Pre-existing public param (see Map Display); logged-in users can also override via the panel.

Developer guide for adding a new admin display toggle: web/src/hooks/useAdvancedDisplaySettings.ts.

Not URL-Controllable

The following features require complex configuration that cannot be easily passed via URL parameters:

Complex Objects

• Custom layer paint/layout properties - Layer styling beyond visibility requires nested objects
• Custom GeoJSON boundaries - Must be fetched from API via slug
• Custom combined taxonomies - Complex hierarchical taxonomy configurations
• Custom filters array - Advanced filter configurations with custom logic

Runtime Features

• Selected items state - Managed internally based on user interaction
• Search term state - User input, not initial URL param
• Current view state - Changes as user toggles map/grid
• Focused/hovered items - Managed by user interaction

Theme-Dependent

• Tooltip styling - Controlled by theme's map.boundaryTooltip config
• Clear button styling - Controlled by theme's map.boundaryClearButton config
• Accent colors - Controlled by theme's accent property
• Card themes - Controlled by theme's cards configuration

API-Dependent

• Specific item IDs - Cannot pre-select specific items by ID via URL
• Custom boundary data - Must use slug to fetch boundary from API
• Taxonomy term details - Fetched from API, including colors and hierarchy

Notes

1. Boolean parameters accept: true, false, 1, 0, "true", "false"
2. Colors can be passed without the # prefix (e.g., dotsColor=ff0000 or dotsColor=%23ff0000)
3. Arrays are comma-separated strings (e.g., vibes=chill,artsy)
4. Theme defaults - Many parameters have theme-based defaults; only specify to override
5. Parameter precedence: URL params > Theme defaults > Built-in defaults
