How to add a string of half-open entry fields

In need to print a label with entry fields.
IMO, this should be a half open box.
A bar at the bottom, half-hight vertical bars on te left and rigth, and open at the top)
I try to create then with insering “lines”, but i can’t get it as expected.
I checked for this symbol in webdings, but unfortunaly not availeble.
Is there a way to show a string of entry fields ?

I think your best bet would be to use lines for this purposes - can you tell us what problems you encountered?
