I'm looking for a module, that changes the workflow of creating a node. I want to be able to have several fields in named group sections so the author of a node has some structure.
But when editing the node the author should be able to quickly jump around the forms.
So for example the Content Type "Article" has the following group sections:
Content > Images > Related Articles
In each section there are fields.
How can I do that? Are there mature modules for that case?
