Duplicated dropdowns where selecting an option disables it for other instances?

[Berkilak]

Hello!

I'm looking to do something (hopefully) simple, but I cannot find a way to do it myself. I have seen it done other places, but I cannot seem to find the options.

Long story short, I need to add multiple instances of a dropdown where people can pick and choose things contained in that list to suit their current needs (it's for an electrical servicing matrix). Once they have selected an option, I would like for that option to disappear from the other instances of the dropdown.

Is this possible?

Yes, but it's not simple at all. An easier solution is to prevent the user from selecting a value that has already been selected in another drop-down using a Validation script.

What are the names of the those fields?
