Need a little more info. When I select business card, what is supposed to populate in size and description? Or, does the user have the option of selecting either size and any description?
I've used formCalc: xfa.host.setFocus("TextField_name") to move to the next text field but it's still not fully "auto tabbing." Used for entering social security numbers on a form similar to your example
The purple bar/highlight fields cannot be removed if the form is interactive. The submit by email can be removed when the form is opened in LC Designer.
