Dear Gofrugal

In shelf Talker

Right now you have given a filter here about Category only.

Means either you type item & item

Or

you choose filter

here you get a list of all items in particular category

here you are providing list of all items even they are not in stock

if item is not available in shelf than what means of the shelf talker/Signage. ?

My suggestion is that  you ad an option of excel sheet import.

in this sheet customer will submit only those items which he has in stock & he need shelf talker

hope you understand.

If not pls call me
