How to show / hide fields based on the other fields

So you want to hide a field if a checkbox on the same Wizard step is not selected?

I’m not sure that can be done at present.

You might be able to achieve that using a conditional step or field, where the 2nd step (or field) only displays if that checkbox is not selected. But this isn’t something I’ve tried. I suspect it only works if the step / field in question comes later in the wizard (i.e. can’t be applied to the current / active step in real time).

See this for some more info on conditional settings:
