Learn how to customize the Simple Tree View component.

Basics

Custom icons

Use the collapseIcon slot, the expandIcon slot and the defaultEndIcon prop to customize SimpleTreeView icons. The demo below shows how to add icons using both an existing icon library, such as Material Icons, and creating an icon from scratch using Material UI's SvgIcon.

Custom toggle animations
