Create a feature highlight as users pass over features to increase discoverability of key features or indicate geographic boundaries.
Feature highlighting is a great way to encourage interaction with your map. Features are highlighted when the mouse cursor is placed above them, the user can then click on the highlight in order to open up the popup containing information about the feature.
To enable to the mouse highlight tool, open the Mango Toolbox, select Visualization tab, and click on Mouse Highlight.
Activate the tool, and select the layer you wish to have the highlight.
Once enabled, features in the selected layer will show a hightlight when the user's mouse passes over them.
