Question on conditional

I have a survey where I want farmers to be able to select the markets they supply from a list. I want them to be able to select multiple markets, if relevant to them. I also need separate follow up questions for each market they select. After those follow ups, i want them to be able to select other markets, or if there is no other market they supply, i want the survey to continue. Is there a page which explains how I can do this? Or perhaps if you could let me know what type of questions these are I could search for info on them. Thanks!

You could approach this in the following way:

Have a checkbox question where the user selects all the markets they supply from a list.

Then have a repeat group where the repeat count is the number of items selected in the checkbox question. You can use count-selected for that.

Inside that repeat group, you should be able to use selected-at and position to reference the current market.
