Hides the currently selected items to the Customization Form.
NuGet Package: DevExpress.Win.Navigation
Layout items can be selected in code via the BaseLayoutItem.Selected property and in customization mode at runtime. Selected items are painted with a different color than regular items.
The HideSelectedItems method hides the currently selected items to the Customization Form. Calling this method is similar to invoking the Hide Item command of the Context Menu (in Customization mode).
