efab Enabled
The enabled state of this ExpandableFab and its label. Disabled ExpandableFabs and labels will be visually distinct and unclickable. Default value is true (enabled).
Usage of this property is preferred over the inherited is/setEnabled methods.
NOTE: If you disable an ExpandableFab and its label, remember to re-enable it before trying to update one of its properties. For example, disabling an ExpandableFab then manually changing its background color will not automatically re-enable the ExpandableFab. It, and its label, will remain disabled.
