The split button triggers a default action when the primary button is clicked, and provides options for switching context when the drop-down button is clicked. It features built-in support for icons and their positioning, varied sizes, disabled items, separators, and RTL text.


You can use different split button sizes (default and small) as required in your application.


Users tend to perceive visual information better than text. The split button has built-in options to position the icon to the left or above the text, or provide an icon-only button.


The pop-up is a toggleable container that holds a list of action items or custom content that will open or close when the button is clicked. You can customize all the items in the pop-up.
