Combo Box - Grouping

This sample demonstrates grouping functionality in the igCombo control.

This sample is designed for a larger screen size.

On mobile, try rotating your screen, view full size, or email to another device.

Grouping functionality allows certain items to be grouped and distinguished by category, such an employee and the department that he belongs to.
