You can hide the title bar, which helps identify the panel stack.
This procedure assumes you have already created a panel stack with a title bar. For instructions, see Inserting and defining panels.
Open the document in the Document Editor.
Select the panel stack in the Layout area.
In the Property List: View section, set Show title bar to False.
Note: If the Property List pane is not displayed, click Property List at the bottom of the panel
on the left. If the panel is not displayed at all, select Property
List from the View menu.
You can also use the Properties and formatting dialog box to hide the panel stack title.
