# Element: Group Role Indicator
|
|
|
|
Toggles the visibility of an indicator based on the unit's current group role (tank, healer or damager).
|
|
|
|
## Widget
|
|
|
|
GroupRoleIndicator - A `Texture` used to display the group role icon.
|
|
|
|
## Notes
|
|
|
|
A default texture will be applied if the widget is a Texture and doesn't have a texture or a color set.
|
|
|
|
