 ## Notes
-To get the desired icons, you can use your dev tools to inspect the rendered icon you want and get its content. Also, you can use any custom icons that are not from the Telerik font (e.g., icons from Bootstrap, Open Iconic, and so on) by specifying the desired font name in addition to the content.
