Is there a way to not allow radio buttons to be clickable if one special radio button is not clicked?
In a form, using radio buttons, there are three choices. I would like it so: if first choice is not clickked, second and third choices should not be clickable.
Alternatively, first choice is shown, when clicked second choice is displayed. When also second choice is clicked, third choice is displayed.
I don't know how to achieve this. Could you please help.
