You can drag the Property Sheet Section component from
the Palette's Layout category to a property sheet on the Visual Designer to add a section to a Property Sheet, or you can right-click a Property Sheet in either the Visual Designer or the Navigator window and choose Add Property Sheet Section. A Property Sheet Section contains Property components and is used primarily as a way to group Property components in a Property Sheet and to provide a label for the group.
You can set the text that appears for a Property Sheet Section by editing its label
component in the Property Sheet Section Properties Window.
A property sheet section contains Property components. A new Property Sheet Section intially has one Property component in it.
To add a property to a section, either drag a Property component to a Property Sheet Section and drop it or right-click the Property Sheet Section component and choose Add Property.
