Filament Map Picker

filament-map-picker is a custom field for Filament 5 that provides an interactive Leaflet.js map for selecting a point location and, optionally, drawing one or more map areas as GeoJSON.

The package is designed to stay flexible. It does not force how you persist latitude, longitude, or area data. Instead, it keeps a predictable field state and lets you map the values however you want through afterStateUpdated() and afterStateHydrated().

Features

• Built for Filament 5
• Powered by locally bundled Leaflet.js and Leaflet Draw
• Default OpenStreetMap tile layer
• Custom tile support through ->tiles([...])
• drag mode and click mode for the point marker
• Optional geocoding search UI
• Optional polygon, rectangle, and circle drawing tools
• Optional multi-shape GeoJSON collections
• Combined point + area state in a single field
• Reactive Livewire-friendly state updates
• Alpine.js powered interaction
• Leaflet layers control for switching tile layers

Requirements

• PHP 8.3+
• Laravel 13+
• Filament 5

Installation

Install the package with Composer:

Then publish Filament assets:

Package Registration

The package supports Laravel auto-discovery through:

In most applications, no manual provider registration is needed.

State Format

Point-only mode

By default, the field stores point coordinates as:

Point + draw mode

When draw mode is enabled, the field stores a combined state:

This makes it easy to keep a marker location and one or more service-area shapes in the same field while still saving them into separate database columns.

Basic Usage

Point-only field

Point + area in a single field

Selection Modes

Drag mode

• the user drags the map
• the marker stays centered
• coordinates are taken from the map center

Click mode

• the user clicks on the map
• the marker moves to the clicked point
• coordinates are taken from that point

Default Tile Layer

If you do not provide custom tiles, the field uses OpenStreetMap automatically.

Built-in default tile definition:

Custom Tile Layers

You can provide your own tile layers with ->tiles([...]). Those definitions are serialized to JSON and passed directly to Leaflet.

Tile behavior:

• if ->tiles() is not called, only osm is available
• if ->tile() is not called, osm is selected by default
• if the selected tile key is invalid, the field falls back to osm
• if more than one base layer exists, Leaflet's built-in layers control is shown on the map
• by default the built-in osm tile is always included
• use ->showDefaultTile(false) if you want to hide the built-in osm tile and only expose your custom tiles

Searchable Mode

Enable geocoding search when you want users to jump quickly to a location:

Behavior:

• users can search for a place or address
• matching results appear in a dropdown list
• selecting a result recenters the map and updates the field state
• selected results are highlighted when reopened

By default, search uses:

You can override it:

Drawing Shapes as GeoJSON

Enable draw mode when you want the user to define areas while keeping a marker location in the same field state.

Notes:

• draw mode stores the field state as ['lat', 'lng', 'geojson']
• the marker location still works as normal
• the drawn area is stored inside geojson
• by default only one drawn shape is kept at a time
• use ->multipleShapes() if you want multiple polygons / rectangles / circles in the same FeatureCollection
• editing or deleting shapes updates the field state automatically
• use afterStateUpdated() / afterStateHydrated() to map latitude, longitude, and geojson into separate database columns

API Reference

->tile(string $tile)

Sets the active tile key.

->tiles(array $tiles)

Registers custom tile layers.

Expected tile format:

->showDefaultTile(bool $condition = true)

Controls whether the built-in osm tile should be included in the available tile list.

->mode('drag|click')

Defines the point marker interaction mode.

->defaultLocation(float $lat, float $lng)

Sets the initial map coordinates.

->zoom(int $level)

Sets the initial map zoom level.

->height(int|string $height)

Sets the map container height.

->markerColor(string $color)

Sets the marker color used in both drag and click modes.

->searchable(bool $condition = true)

Enables place search.

->searchPlaceholder(string $placeholder)

Overrides the search input placeholder.

->searchProviderUrl(string $url)

Overrides the geocoding endpoint used by the search box.

->searchResultLimit(int $limit)

Controls how many search results are shown in the dropdown.

->drawable(bool $condition = true)

Enables shape drawing tools and switches the field state into combined point + GeoJSON mode.

->drawTools(array $tools)

Controls which draw tools are available. Supported values are polygon, rectangle, and circle.

->fitDrawBounds(bool $condition = true)

Controls whether the map should automatically fit to the drawn shapes after create or edit.

->multipleShapes(bool $condition = true)

Allows the field to keep multiple drawn shapes inside the GeoJSON FeatureCollection.

->showAreaMeasurement(bool $condition = true)

Shows area labels directly inside the map for each drawn shape when draw mode is enabled.

->areaMeasurementUnit('m2'|'ha')

Controls the unit used for the displayed area measurement.

Notes

• The package does not force any persistence strategy for latitude, longitude, or area GeoJSON
• You are free to map the field state into any schema structure you prefer
• Custom tiles are the developer's responsibility, including availability and usage terms
• Search providers are the developer's responsibility, including availability and usage terms
