On Open Change

The onOpenChange prop is used to handle the changes when a submenu is opened or closed.

Props​

onOpenChange?: (open: boolean) => void

With Parameter​

This example demonstrates the onOpenChange prop with a boolean parameter. When the submenu is opened or closed, the onOpenChange function is called with a boolean parameter indicating the new state of the submenu.

Example​

/vertical-menu/submenu/on-open-change/with-params

Toggle Dashbord Submenu to see the change


Submenu is closed
