In an XML file:

<delete model="ir.ui.menu" id="hr.menu_hr_department_tree" />

You can find the name for any Menu under Settings --> User Interface --> Menu Items and, in Developer Mode, open the menu form view and select View Log from the Debug Menu.

The part of the XML ID to the right of the period is what you want to search for.

hi,we shoould add this line in the inherite view : <delete model="ir.ui.menu" id="hr.menu_hr_department_tree"/>
