Hi! I am a beginner! I am working on a form and I stumbled upon a problem: I want to make a subcategory. For example example I have a check box and if the person checks it I want him to fill in a text box, but right away(when he checks the text box should appear, otherwise it should not appear).
(check)is it on the road?
if/when on the road is checked: which road?(text)
