CSS

• Style sheet name: MuiTreeView.
• Style sheet details:

Rule name	Global class	Description
root	.MuiTreeView-root	Styles applied to the root element.

You can override the style of the component thanks to one of these customization points:

• With a rule name of the classes object prop.
• With a global class name.
• With a theme and an overrides property.

If that's not sufficient, you can check the implementation of the component for more detail.
