Idea Summary
I would like the modal dialog page to have an option to hide the Title Bar. At the moment, I have to use a bit of CSS to hide the title bar. And when I do this, I have to manually calculate and set the height of the modal dialog page. 

Use Case
Simple update form for one or two items where I do not want the title bar to show. Below is an example of a modal dialog page where the title bar has been hidden using css. The height also adjusted so that it is not too long. 

Preferred Solution (Optional)
It should be an an page attribute that can be turned on/off.
