Tried setting the button heights to 0 and they went massive. This may be because I have images on them
Currently I have 2 Menus= one for the POS and one for the Tablet (Both with different button heights)
I then have four departments 2 Restaurant and 2 Takeaway
1 Restaurant and 1 Takeaway is set to the POS Menu and
1 Restaurant and 1 Takeaway is set to the Tablet Menu
Then in the user roles I have restricted the POS user to only view the POS Menu departments
and on the Tablet User Role I have allowed the Tablet departments.
Only downside of this procedure is when printing reports, you get quite a few departments showing up instead of the 2.
