# Design Time

The AjaxManager delivers the **Smart Tags** options from the context menu.

To display the **Smart Tags**, right-click the control and select **Show Smart Tag**, or click the small rightward-pointing arrow located in the upper right corner of the control.

The **Smart Tags** for the [AjaxPanel](https://www.telerik.com/products/aspnet-ajax/documentation/controls/ajaxpanel/overview) and [AjaxManager](https://www.telerik.com/products/aspnet-ajax/documentation/controls/ajaxmanager/overview) are nearly identical. The AjaxManager **Smart Tag** provides a **Configure Ajax Manager** link and a **Choose DefaultLoadingPanelID** drop-down list. The **Configure Ajax Manager:** displays the AjaxManager Property Builder.
