Is it possible to repeat a field inside an instrument an infinite number of times?
In my exemple, I have to insert infos about material used (not listed) in a procedure. I can have only 1 item but sometimes maybe 10 items.
The best way for doing this may be a button next to the textfield saying "add new material" and a new text field to appear... Is this possible or do I have to preset a given number of fields with a different name (e.g. material_1, material_2, material_3,...)?
Thanks for help!

Dear Yannick,
That's a very good question and you just pointed out one of REDCap drawbacks as this is "technically" not possible.
Still, you have two options:
1. As you suggested, you could preset a given number of fields and use branching logic to display for e.g. a new field as soon as the previous is completed. Or eventually use a question on top where the user has to specify how many "new material" he/she is going to add and use branching logic so that the right amount of items appear.
2. You isolate the question(s) related to "new material" in a separate instrument and make the instrument repeatable (by going to "Project Setup" and enabling the "Reepeating instruments" functionality:
). As such, you will be able to repeat the instrument (and the item it contains) an infinite number of times.
Option 2 surely is the way to go if you and your study team plan to fill in the study data manually (using 
), but if the item should be part of a Survey, I would go for Option 1 so that everything holds in one page.
Best,
C.

Dear Corentin,
Many thanks for your quick and useful answer!
As the instrument in which the material has to be specified is already a repeatable instrument, I guess the easier option is option 1.
Kind Regards,
Yannick
