usability: checkboxes weren't visible until I added a valid URL in formbuilder
I was trying to work out how to make a form accessible from the front end of a site.
The checkbox I was looking for was hidden until I added a valid URL which is bad for discoverability of functionality.
It might be better handled in validation.
