# Collapsed menu

Use collapsable vertical menu with layout sider. Use `collapsed` to control collapse status of menu. You must set `collapsed-width` to make it collapse in a right manner. There are still some other collapse related props you can modify: `icon-size`, `collapsed-icon-size`. For details see API table at the bottom of the page.
