hi i want to create navigation pane like we often see in Outlook 2007.

like there are buttons like Mail, Tasks, Calendar etc.When we start down shrinking the controls overlapped ant their respective icons show in to the the lowest panel.

Now i want to create such type of control in my application.

How can i do this.

Do you mean the Expander control? WPF Expander Control
