"ADD" property

is it possible to have the option “Set conditions for when ADD is allowed” for the ADD parameter.
This makes it possible to make a single page for different users.
Otherwise I have to make 2 tabs with different Visibility conditions.

Not possible as of now, but you can change it to a details view and add a form button, then display the inline list of items in the tab under.

Thank you for your reply.
Yes that was my first option.
But I want to keep a List style tab for tablet or full screen display (very practical)

Then two separate tabs with different visibility conditions is your best bet, because we don’t have a condition for adding button now. Hope they roll it out soon.
