How can I collect multiple answers for the same question in ODK build?
Hi @Julian_gp and welcome to the forum! When you get a chance, please introduce yourself on this forum thread.
Can you provide some more details? Do you mean a question with a list of answer options, and the respondent can select more than one option for their answer?
If that is the case, you will want to add a "Select Multiple" type question.
You might want to try using XLSForm. It takes a little bit more work to learn than ODK Build, but it makes it easier to create more complex forms. Read more about it at these two links:
I mean, for example, if the question is "Engineers" that the user can add as many engineers as he wants, without having to personally create "Engineer1", "Engineer2"...
For that you'll need to use a repeat. I don't think it can be done in Build.
