In an interactive layer, features are highlighted when the user hovers their mouse over them.
Here's how to make a layer interactive:
- Click the LAYER ADMIN icon.
- Select the layer you wish to be interactive.
- Click the "Edit" button in the "Style" category.
- Toggle on "Highlight on hover".
Keep in mind that only layers that have less than 5000 features are able to be set as interactive layers.
