Simple Tree View - Customization

Learn how to customize the simple version of the 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.

  • Main
    • Hello
    • World
    • Something something

Custom toggle animations

Use the TransitionComponent prop 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.

  • Main
    • Hello
    • World
    • Something something

Custom styling

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

  • Main
    • Hello
    • World
    • Something something

Adding custom content

Use the ContentComponent prop and the useTreeItemState hook to replace the Tree Item content with an entirely custom component. The demo below shows how to add an avatar and custom typography elements.
