Show/hide part of form

If you want to show or hide fields based on selections a user makes you would use Conditional Logic. Conditional Logic allows you to show (or hide) fields when a user makes a selection on a drop down, radio button or checkbox field.

You enable conditional logic on the field you want to show (or hide) by editing it, going to the Advanced Tab and enabling and configuring Conditional Logic.

You need to have a drop down, radio button or checkbox field on your form for the conditional logic to be triggered by that field.

You would have to use the HTML fields to add some additional markup around the hidden section of your form. You would need to close the initial UL that's used for the main form structure, start a div element, re-open the list then close the list again with custom markup in an HTML field.

There's an example here of what I'm talking about..

Once you've successfully added the div wrapper around the portion of your content you want to hide, you'll have to add some jQuery to make it work. There's a ton of ways to do that so you'll just have to research which is the best for you.
