An accordion is a user interface pattern that allows users to expand or collapse sections of content. If you have a lot of content on your page, divided into sections, you may want t make each section expandible/collapsible using an accordion.
Accordions can be set up in various places, such as itineraries, static pages, FAQ sections, etc.
For example, if you want to set it up in the Itinerary section, navigate to Products > Trips > Edit trips > Detailed Itinerary. Here, add the content and select the text that will be displayed as a heading. Then, choose the styles option and select "Accordion heading". For the content, select the content text and from the styles option, choose "Accordion content" and Save the changes.
The accordion will be displayed as shown in the screenshot below.
