If you want a button to act like a category, then:
- Create a button group.
- Add items as Type S(Stock card).
- Allocate pictures.
- Add the new button group to the main group with Type B (Button group).
- If the Type is S as in stock cards, then pictures can be assigned to individual buttons.
Please note that a button cannot have both text and a picture. If the user wants both of these, then they have to be edited using a picture editor and then replaced for each button accordingly.
Very important: install the below software on every POS so that pictures will be displayed properly. During the installation, all POS programs must be closed.
