You can use these plugin widgets to show category/menu accordion on your site. Go to your site admin > Appearance > Widgets. Here you will see our custom widgets for the accordions. One for showing categories and another for menu accordion.
Just add the widget to your sidebar area and configure the widget settings as you need.
Also, you can put our shortcodes on your site to show the accordion. Please see the shortcodes and shortcode parameters section for details.
