# About the Task Pane

The task pane is a component that serves as a generic container for content or User Interface for custom functionality.

Functionality is added by creating InvokeURL widgets and adding them to a toolbar or menu.

The InvokeURL widget loads your custom page content into the page for the user, and provides access to the current server-side session, map name and other critical runtime information.

Task Pane content has access to the viewer API allowing for interaction with the main map viewer.
