To add layers to a base map:
- Click the 'Maps' icon on the left-hand side of the screen.
- Hover over the base map that you'd like to edit and click the edit icon (pencil icon) to the right of the base map's name.
- Click "ADD LAYERS".
- Search for the layer that you'd like to add to the base map by using the search bar, or scrolling through the data.
- Select the layer(s) that you would like to add to the base map and click "SAVE".
Your base map now has layers!
*Note: The order in which you see the layers under "ADD LAYERS" will determine how the layers are organized on the base map. If you would like to change the order, hover over the layer in edit mode and click the Up or Down arrows to move them. If you would like to remove the layer, click the 'trash' icon.
