The polygon shapes can be highlighted via user interaction if the enable property of highlightSettings is set to true. The following properties are available in highlightSettings to customize the polygon shape when it is highlighted.
- fill - It is used to change the color of the highlighted polygon shape.
- opacity - It is used to change the opacity of the highlighted polygon shape.
- border - This property is used to change the color, width, and opacity of the border of the highlighted polygon shape.
To use the polygon feature, the Polygon module must be injected, as described in this link.
The following example shows how to highlight a polygon shape on a geometry map.

On mouse over or touch end event, the tooltip is used to get more information about the layer, bubble, or marker. It can be enabled separately for layer or bubble or marker by using the visible property of tooltipSettings as true. The valuePath property in the tooltip takes the field name that presents in dataSource and displays that value as tooltip text. The tooltipDisplayMode property is used to change the display mode of the tooltip in Maps. Following display modes of tooltip are available in the Maps component. By default, tooltipDisplayMode is set to MouseMove.
- MouseMove
- Click
- DoubleClick
