## ### ### props | Prop | Type | Default | Required | Description | | ---- | :--: | :-----: | :------: | :----------: | | id | `string` | `none` | `true` | A string that uniquely identifies the source in the style to which it is added. | | sourceID | `string` | `MapboxGL.StyleSource.DefaultSourceID` | `false` | The source from which to obtain the data to style.
If the source has not yet been added to the current style, the behavior is undefined.
Inferred from parent source only if the layer is a direct child to it. | | sourceLayerID | `string` | `none` | `false` | Identifier of the layer within the source identified by the sourceID property from which the receiver obtains the data to style. | | aboveLayerID | `string` | `none` | `false` | Inserts a layer above aboveLayerID. | | belowLayerID | `string` | `none` | `false` | Inserts a layer below belowLayerID | | layerIndex | `number` | `none` | `false` | Inserts a layer at a specified index | | filter | `array` | `none` | `false` | Filter only the features in the source layer that satisfy a condition that you define | | minZoomLevel | `number` | `none` | `false` | The minimum zoom level at which the layer gets parsed and appears. | | maxZoomLevel | `number` | `none` | `false` | The maximum zoom level at which the layer gets parsed and appears. | | style | `union` | `none` | `false` | Customizable style attributes | ### styles * visibility

___ #### visibility Name: `visibility` #### Description Whether this layer is displayed. #### Type `enum` #### Default Value `visible` #### Supported Values **visible** - The layer is shown.
**none** - The layer is not shown.
___ #### backgroundColor Name: `backgroundColor` #### Description The color with which the background will be drawn. #### Type `color` #### Default Value `#000000` #### Disabled By `backgroundPattern` #### Expression Parameters: `zoom` ___ #### Name `backgroundColorTransition` #### Description The transition affecting any changes to this layer’s backgroundColor propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### backgroundPattern Name: `backgroundPattern` #### Description Name of image in sprite to use for drawing an image background. For seamless patterns, image width and height must be a factor of two (2, 4, 8, ..., 512). Note that zoomDependent expressions will be evaluated only at integer zoom levels. #### Type `resolvedImage` #### Expression Parameters: `zoom` ___ #### Name `backgroundPatternTransition` #### Description The transition affecting any changes to this layer’s backgroundPattern propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}` ___ #### backgroundOpacity Name: `backgroundOpacity` #### Description The opacity at which the background will be drawn. #### Type `number` #### Default Value `1` #### Minimum `0` #### Maximum `1` #### Expression Parameters: `zoom` ___ #### Name `backgroundOpacityTransition` #### Description The transition affecting any changes to this layer’s backgroundOpacity propery. #### Type `{ duration, delay }` #### Units `milliseconds` #### Default Value `{duration: 300, delay: 0}`
