React Accordions:

React Accordion with Separated Shadowy Items

These accordions can be used to categorize the steps of a task or to better categorize the content. These accordions have a triangular icon to the left of the title of each accordion. Click on each accordion to turn the icon down, and normally this triangle is to the right. The titles and texts on this accordion are black. The background of the accordion is white. A dividing line separates the title from the accordion texts.
