Re: Removing "layout" property — AttributeError: manage_delProperty

Did you find out, why the "Display" menu disappears?

If not, maybe you find some answer in plone.app.contentmenu.menu
module's DisplaySubMenuItem. There's a "disabled" method. I overwrote it
once to be displayed also in folder_contents views like so:
