Hi @kentchan4,
You can:
- add Other (value is 'other' for example) to the list of choices for your choicequestion of the Choose One widget.
Follow-up Question select 'other' (We are still in the Choose One widget!) - add a text question widget with relevance : selected(/data/choicequestion, 'other')
Label your text question something like Please specify other ...
I wanted to add a good example given by @yanokwa in this forum (Colors.odkbuild) but I couldn't find where and the website won't let me upload a file with a .odkbuild extension.
Sorry!
I just found the link: https://forum.getodk.org/t/help-on-odk-build-how-can-i-create-other-on-multiple-choices/6533
