Show/hide fields in a form based on the value of a checkbox Is there a way to hide a specific or specifics fields in Drupal when you create content until you checked a checkbox?

Now it looks like this:


I need something like this:


But I need some checkboxes to decide if I have a certain field to show or not. Like this:

(Fieldcollection item 'some information' is showing up now because I checked the checkbox before the label)

Is there a module for this?

What would be nice is if all fields only become mandatory if you checked a checkbox.
You can use module conditional fields if you want to do this node form
