Accordion allows you to customize its appearance in different ways based on your requirements. It provides various properties which can be used to customize different elements of the Accordion control such as its header, icon and content area. The following sections explain different customizations that can change the appearance of the Accordion control.
Header Customization
You can customize the header of the Accordion control by modifying the header of the expanders in each accordion pane using HeaderTemplate property of the C1Expander class. This property sets a template for the header using the DataTemplate class.
The following image showcases customized headers of the Expanders used in the Accordion control.
The following code showcases customization of the Expander headers in the Accordion control. This example uses the sample created in Quick Start.

Fill Accordion
Accordion allows you to specify whether the expanded item should fill the empty area in the control using Fill property of the C1Accordion class. The following GIF displays how the Accordion control behaves when the Fill property is set to True.
The following code demonstrates how to fill the empty area in the Accordion control. This example uses the sample created in Quick Start.
Icon Alignment
Expand Icon appears next to the header which when clicked expands the content area of the Accordion control. By default, the expand icon is aligned on the right side of the header. However, you can change the alignment of the expand icon as per your requirements using ExpandIconAlignment property of the C1Accordion class. The ExpandIconAlignment property changes the alignment of the expand icon using the ExpanderIconAlignment enumeration.
The following image shows the expand icon aligned on the left of the header of the Accordion control.
The following code shows how you can change the alignment of the expand icon to "Left". This example uses the sample created in Quick Start.
