# LegendItem

***

A legend item, which often represents a sub-class of features in a\
layer in the case of categorical or classed layers.

## Properties

### title

> **title**: `string` | `string`\[]

The title of the legend item.

***

### titleDependsOnZoom

> **titleDependsOnZoom**: `boolean`

Whether the title depends on the zoom level or not. If it does, you\
need to call [\`getLegendItem\`](/js-sdk-api-reference/layers/layerscontroller.md#getlegenditem) when the zoom level changes.

Note that as the zoom level changes, the [\`onLegendItemChange\`](/js-sdk-api-reference/layers/layerscontroller.md#onlegenditemchange) handler\
will not be called, so you need to call [\`getLegendItem\`](/js-sdk-api-reference/layers/layerscontroller.md#getlegenditem) yourself.

***

### visible

> **visible**: `boolean`

Whether the legend item is visible or not.

***

### id

> **id**: `string`

The id of the legend item.

***

### layerId

> **layerId**: `string`

The id of the layer the legend item belongs to.
