JavaScript/jQuery Select Box - Customize Drop-Down Button
Use the dropDownButtonTemplate to customize the drop-down button.
This demo illustrates three customization cases:
-
Custom image
Declare animg
element in the template. -
Load indicator
Declare the load indicator and a regular icon in the template. Display the load indicator while hiding the icon, and vice versa. -
Icon that depends on the selected value
Declare the default and the selected item's icon in the template. If there is a selected item, display its icon; otherwise, show the default icon.
