How to change the menu definition right from global admin to subwiki local admin?

dear every one:
forgive my poor english first.
i defined a wiki farm with many subwikis,and each subwiki have its own menu
i want the administor of subwiki to define its own menu
but i found ,the menu disappeared when a local administor changed the subwiki menu ,but if i login as a superadmin ,and save the menu again ,the menu will be back
so ,what can i do ?

Hi, if you’re talking about https://extensions.xwiki.org/xwiki/bin/view/Extension/Menu%20Application make sure you set the right visibility (see https://extensions.xwiki.org/xwiki/bin/view/Extension/Menu%20Application#HMenuUsage ).

thanks alot ,i solved it as the page suggested,i give the programming right to subwiki admin
