I need help with some grid questions regarding survey123. I'm trying to create a form (survey), with a 2 subgroups. I typed 'w4' into their appearances to try and get them to stretch to the entire form, but they just end up stacking up next to each other. Please advise.
What version of Survey123 Connect and field app are you using?
Can you share your XLSForm (xlsx file and any media folder files) so we can take a closer look?
With grid theme you need to ensure the w appearance is applied to all groups and questions inside those groups if you want to set different widths.
Please refer to:
There is a sample in Connect that also demonstrates using groups and repeats with grid theme.
