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, popover-body-style. For details see API table at the bottom of the page.
