I want to create a dynamic form in a Plone 4.3 site with PloneFormGen 1.7.15. Dynamic means that I want to disable an option, when a certain number of participants have chosen this option.
Is it possible the set the attribute "disabled" to a radio button? I have not found a way to do it manually.
I was looking at the article How can I generate a registration number in PloneFormGen, using a TALES Expression? which show how to implement a counter. But I have no idea, how to actually change the radio button, when the condition is met. Any hints on that?
I used http://plone.org/products/collective.signupsheet for the form. It has the functionality to limit the number of registrants for an event. The solution I thought of when asking the question became obsolete.
