Rich Tree View - Customization

Learn how to customize the Rich Tree View component.

Basics

Custom icons

Use the collapseIcon slot, the expandIcon slot and the defaultEndIcon prop to customize the Tree View 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 SVG Icon component.

Custom toggle animations

Use the groupTransition slot on the TreeItem to pass a component that handles your animation.

The demo below is animated using Material UI's Collapse component together with the react-spring library.

Custom styling

Use treeItemClasses to target internal elements of the Tree Item component and change their styles.

Custom label

Use the label slot to customize the Tree Item label or to replace it with a custom component.

The slotProps prop allows you to pass props to the label component. The demo below shows how to pass an id attribute to the Tree Item label:

The slots prop allows you to replace the default label with your own component: The demo below shows how to add a tooltip on the Tree Item label:

Headless API
