Markers and controls

Join the Mapbox Developers Discord Communityarrow-right

User interface elements that can be added to the map. The items in this section exist outside of the map's canvas element.

AttributionControl

githubsrc/ui/control/attribution_control.js

An AttributionControl control presents the map's attribution information. Add this control to a map using Map#addControl.

new AttributionControl(options: Object?)

Parameters

options(Object?)(default {})
NameDescription
options.compact
boolean?		If true , force a compact attribution that shows the full attribution on mouse hover. If false , force the full attribution control. The default is a responsive attribution that collapses when the map is less than 640 pixels wide. Attribution should not be collapsed if it can comfortably fit on the map. compact should only be used to modify default attribution when map size makes it impossible to fit default attribution and when the automatic compact resizing for default settings are not sufficient .
options.customAttribution
(string | Array<string>)?		String or strings to show in addition to any other attributions. You can also set a custom attribution when initializing your map with the customAttribution option .

Example

const map = new mapboxgl.Map({attributionControl: false})
    .addControl(new mapboxgl.AttributionControl({
        customAttribution: 'Map design by me'
    }));

FullscreenControl

githubsrc/ui/control/fullscreen_control.js

A FullscreenControl control contains a button for toggling the map in and out of fullscreen mode. See the requestFullScreen compatibility table for supported browsers. Add this control to a map using Map#addControl.

new FullscreenControl(options: Object?)

Parameters

options(Object?)
NameDescription
options.container
HTMLElement?		container is the compatible DOM element which should be made full screen. By default, the map container element will be made full screen.

Example

map.addControl(new mapboxgl.FullscreenControl({container: document.querySelector('body')}));

GeolocateControl

githubsrc/ui/control/geolocate_control.js

A GeolocateControl control provides a button that uses the browser's geolocation API to locate the user on the map. Add this control to a map using Map#addControl.

Not all browsers support geolocation, and some users may disable the feature. Geolocation support for modern browsers including Chrome requires sites to be served over HTTPS. If geolocation support is not available, the GeolocateControl will show as disabled.

The zoom level applied depends on the accuracy of the geolocation provided by the device.

The GeolocateControl has two modes. If trackUserLocation is false (default) the control acts as a button, which when pressed will set the map's camera to target the user location. If the user moves, the map won't update. This is most suited for the desktop. If trackUserLocation is true the control acts as a toggle button that when active the user's location is actively monitored for changes. In this mode the GeolocateControl has three interaction states:

  • active - The map's camera automatically updates as the user's location changes, keeping the location dot in the center. This is the initial state, and the state upon clicking the GeolocateControl button.
  • passive - The user's location dot automatically updates, but the map's camera does not. Occurs upon the user initiating a map movement.
  • disabled - Occurs if geolocation is not available, disabled, or denied.

These interaction states can't be controlled programmatically. Instead, they are set based on user interactions.

new GeolocateControl(options: Object?)

Parameters

options(Object?)
NameDescription
options.fitBoundsOptions
Object
default: {maxZoom:15}
A Map#fitBounds options object to use when the map is panned and zoomed to the user's location. The default is to use a maxZoom of 15 to limit how far the map will zoom in for very accurate locations.
options.geolocation
Object
default: window.navigator.geolocation
window.navigator.geolocation by default; you can provide an object with the same shape to customize geolocation handling.
options.positionOptions
Object
default: {enableHighAccuracy:false,timeout:6000}
A Geolocation API PositionOptions object.
options.showAccuracyCircle
Object
default: true
By default, if showUserLocation is true , a transparent circle will be drawn around the user location indicating the accuracy (95% confidence level) of the user's location. Set to false to disable. Always disabled when showUserLocation is false .
options.showUserHeading
Object
default: false
If true an arrow will be drawn next to the user location dot indicating the device's heading. This only has affect when trackUserLocation is true .
options.showUserLocation
Object
default: true
By default a dot will be shown on the map at the user's location. Set to false to disable.
options.trackUserLocation
Object
default: false
If true the GeolocateControl becomes a toggle button and when active the map will receive updates to the user's location as it changes.

Example

map.addControl(new mapboxgl.GeolocateControl({
    positionOptions: {
        enableHighAccuracy: true
    },
    trackUserLocation: true,
    showUserHeading: true
}));

IControl

githubsrc/ui/map.js

Interface for interactive controls added to the map. This is a specification for implementers to model: it is not an exported method or class.

Controls must implement onAdd and onRemove, and must own an element, which is often a div element. To use Mapbox GL JS's default control styling, add the mapboxgl-ctrl class to your control's node.

Example

// Control implemented as ES6 class
class HelloWorldControl {
    onAdd(map) {
        this._map = map;
        this._container = document.createElement('div');
        this._container.className = 'mapboxgl-ctrl';
        this._container.textContent = 'Hello, world';
        return this._container;
    }

    onRemove() {
        this._container.parentNode.removeChild(this._container);
        this._map = undefined;
    }
}
// Control implemented as ES5 prototypical class
function HelloWorldControl() { }

HelloWorldControl.prototype.onAdd = function(map) {
    this._map = map;
    this._container = document.createElement('div');
    this._container.className = 'mapboxgl-ctrl';
    this._container.textContent = 'Hello, world';
    return this._container;
};

HelloWorldControl.prototype.onRemove = function () {
    this._container.parentNode.removeChild(this._container);
    this._map = undefined;
};

new Marker(options: Object?, legacyOptions: Options?)

Parameters

options(Object?)
NameDescription
options.anchor
string
default: 'center'
A string indicating the part of the Marker that should be positioned closest to the coordinate set via Marker#setLngLat . Options are 'center' , 'top' , 'bottom' , 'left' , 'right' , 'top-left' , 'top-right' , 'bottom-left' , and 'bottom-right' .
options.className
string?		Space-separated CSS class names to add to marker element.
options.clickTolerance
number
default: 0

options.color
string
default: '#3FB1CE'
The color to use for the default marker if options.element is not provided. The default is light blue.
options.draggable
boolean
default: false
A boolean indicating whether or not a marker is able to be dragged to a new position on the map.

HTMLElement?		DOM element to use as a marker. The default is a light blue, droplet-shaped SVG marker.
options.occludedOpacity
number
default: 0.2
The opacity of a marker that's occluded by 3D terrain.
options.offset
PointLike?		The offset in pixels as a PointLike object to apply relative to the element's center. Negatives indicate left and up.
options.pitchAlignment
string
default: 'auto'
'map' aligns the Marker to the plane of the map. 'viewport' aligns the Marker to the plane of the viewport. 'auto' automatically matches the value of rotationAlignment .
options.rotation
number
default: 0
The rotation angle of the marker in degrees, relative to its respective rotationAlignment setting. A positive value will rotate the marker clockwise.
options.rotationAlignment
string
default: 'auto'
The alignment of the marker's rotation. 'map' is aligned with the map plane, consistent with the cardinal directions as the map rotates. 'viewport' is screenspace-aligned. 'horizon' is aligned according to the nearest horizon, on non-globe projections it is equivalent to 'viewport' . 'auto' is equivalent to 'viewport' .
options.scale
number
default: 1
The scale to use for the default marker if options.element is not provided. The default scale corresponds to a height of 41px and a width of 27px .
legacyOptions(Options?)

Example

// Create a new marker.
const marker = new mapboxgl.Marker()
    .setLngLat([30.5, 50.5])
    .addTo(map);
// Set marker options.
const marker = new mapboxgl.Marker({
    color: "#FFFFFF",
    draggable: true
}).setLngLat([30.5, 50.5])
    .addTo(map);
