I realise what field sets are as they can group parts of your webform together. What I am looking for though is to have subheadings within those fieldsets.
I've been trying to find tutorials about this but all I can find is tutorials on how to build a simple webform with just a title, description and then label-field pairs.
Edit: Say I want a form that calculates taxes for someone and I want to start off with a fieldset that has a couple of radiobuttons like male/female, I live rural/I live in the city and whatnot. Then I want some label/textfield pairs like name address phone, etc... Then within the same fieldset I would have a title that says 'do you have a secondary address?' and have that be the title for a subset of fields with again address and zipcode, etc..
