Toolbar button icons improve the usability of a system as they graphically prove a queue to the system user to perform system actions. In K2, generic toolbar buttons exist to describe an action which can be performed. Examples of these icons include; Add, Delete, Check In and Check Out. However, there may be a requirement to use a specific icon to describe an action which is not included in the standard ‘out of the box’ icon list.

This blog will show you how you can implement custom icons for toolbar buttons using a font based icon library. In this blog we have used “Font Awesome” icon library. There are several other icon libraries you can use, such as Bootstrap Icons and Google Icons. The following example is implemented in K2 Five, but is also applicable for other versions of K2.
