Customizing content edit forms

You can create a customized content edit form for a particular content type, and then assign the form to a role or role-site combination. This feature is useful when you want to show or hide certain widgets or fields depending on a user’s role, or if you want to make some widgets or fields read-only. For example, for articles, you can have one version of the content edit form without the Overrides widget for your users in the reporter role, and another version of the form that includes the Overrides widget for your SEO administrators.
