I am using the UDD to let users show what type of product they have available.  However, when it comes to selecting the product(s) they have in each category they may need to select more than one.

EG.

Milk, eggs, cheese etc...

If I set it to use radio buttons then only can be selected, alternatively I can set an individual question for each item (but this would mean setting up 100 odd questions (4 questions with app. 20 options each).

Anyone know how to do this, or a better option (the survey module won´t help)

I tried to find another thread which discussed this, but couldn´t.  Apologies if there is already one.

Thanks in advance
