# C1OutlookBar Features

## Content

The following are some of the main features of [C1OutlookBar](/componentone/api/wpf/online-outlookbar/dotnet-framework-api/C1.WPF.OutlookBar.4.6.2/C1.WPF.OutlookBar.C1OutlookBar.html) that you may find useful:

* **Microsoft Outlook-style UI**
    Group content and navigation menus into distinct categories just like the navigation system used in Microsoft Outlook 2007 and 2010. This model helps you organize content and allows end-users to navigate quickly.
* Office 2007 and 2010 Themes
    **C1OutlookBar** supports several different Office 2007 and 2010 themes including blue, black and silver. These themes work just like standard Silverlight themes. See the [Themes](/componentone/docs/wpf/online-outlookbar/outlookbarforwpflayo/themes) topic of this documentation for more information.
* Expand/Collapse
    Enable the **C1OutlookBar** control to collapse to the left or right of the page. See [Expanding and Collapsing C1OutlookBar](/componentone/docs/wpf/online-outlookbar/workingwithoutlookba1/expandingandcollapsi) for more information.
* Stackable Buttons
    Use the splitter bar to stack buttons into the collapsed item panel located at the bottom of the control. When buttons overflow they will appear in the drop-down menu for selection.
* Flexible Data Binding
    **C1OutlookBar** is an **ItemsControl** that can be bound to any list of objects of any data type using DataTemplates to create a visual representation of the items. See the [Adding an Image to a C1OutlookItem](/componentone/docs/wpf/online-outlookbar/outlookbarforwpftask/addinganimagetoac1ou) topic for an example.
* **Easily Change Colors with ClearStyleC1OutlookBar**
     supports **ComponentOne ClearStyle technology** which allows you to easily change control brushes without having to override templates. By just setting a few brush properties in Visual Studio you can quickly style each part of the accordion. See [OutlookBar ClearStyle Properties](/componentone/docs/wpf/online-outlookbar/outlookbarforwpflayo/componentoneclearsty/outlookbarclearstyle) for more information on the ClearStyle technology.
