Customize Icon
You can customize the Header icon using customIcon property. This property has two features such as header and selectedHeader. By default, the classes of header and selectedHeader are e-collapse and e-expand respectively.
You can change the + and - symbols in the Accordion header, that are the default icons with Up or Down arrow icons.
Up or Down arrow icons are available in e-arrowheadup and e-arrowheaddown classes respectively in the ej.widgets.core.min.css stylesheets from the sample.
You can set the Up or Down arrow icon to Accordion header, by adding e-arrowheadup and e-arrowheaddown class to selectedHeader and header properties respectively.
