menu label: ->{ User.some_method }

  • :id (String) —

  • :url (String, Symbol, Proc) —

    The URL this item will link to.

  • :priority (Integer) —

    The lower the priority, the earlier in the menu the item will be displayed. Default: 10

  • :if (Symbol, Proc) —

    This decides whether the menu item will be displayed. Evaluated on each request.
