Document Containers are generic “wrappers” that the body of pleadings can be inserted into. For example, I have a document container which has only the court caption, a body insertion field, and my esignature and firm information block. Then on forms i.e. pleadings I point the individual form to the document container with the caption etc. In this way I do not have to duplicate the “container portion” in each form.
