When the widget is bound to a remote data source, it can display a loading indicator while data is loading.
To enable the automatic loading indicator, set the enabled option to true.
This option supports the following colors:
- Hexadecimal colors
- RGB colors
- RGBA colors
- Predefined/cross-browser color names
- Predefined SVG colors
The loading indicator's visibility is tied to the DataSource's load method: it appears when the method's execution starts and hides when the execution is complete. The TreeMap calls the method internally.
If you want to change the loading indicator's visibility, use the show option.
