In Accordion control, users can set the direction in which the accordion pane would expand to display the items. By default the Accordion expands in downward direction and the control expands from top to bottom.  The C1Accordion class provides the ExpandDirection property for this purpose. The ExpandDirection enumeration lets the user expand the Accordion in four directions: Left, Right, Up or Down direction. This feature lets the user fit the accordion control into a variety of application UIs.

The code snippet below illustrates how to set the direction for expansion in Accordion for WPF control as 'right':

<c1:C1Accordion x:Name="accordion" ExpandDirection="Right" Width="300" Margin="25">
</c1:C1Accordion>

accordion.ExpandDirection = C1.WPF.Accordion.ExpandDirection.Right;
