In this blog, I am going to explain how to use salesforce lightning: accordion component. A lightning:accordion component groups related content in a single container. Only one accordion section is expanded at a time. When you select a section, it’s expanded or collapsed. Each section can hold one or more Lightning components. In this blog, I am going to show the list of books by its category as an accordion.

({ doInit : function(component, event, helper) { var action = component.get("c.getBooksByAllCategories"); action.setCallback(this, function(a) { component.set("v.bookList", a.getReturnValue()); }); $A.enqueueAction(action); } }) |
You can see final accordion in the below image.
