This page has an example of the macro "ChildPagesAsAccordion" macro. Accordions are useful when you have a lot of information you want to provide to the viewer but you want to limit clutter. Steps on how to use this macro are below.
Insert the macro named "ChildPagesAsAccordion". You can do this by going to the main text editor and clicking the 6th button (looks like 2 gear cogs) from the right at the top. This will expand out a panel to the right with a drop down you can use to select between all your available macros. Once you click on the "ChildPagesAsAccordion" option from the drop down, the panel will prompt you to choose a content folder. You can select any directory in Umbraco, but for now let's stick to this content page we are on currently. Finally, click submit at the bottom right of the panel and then click save and publish near the bottom right of the screen.
Once, the page is saved we will need to make our child pages. Simply create additional content pages under this page (or whatever directory you chose to pull data from for your macro). Each of these pages will need to have a title and some text else the entry wont show up correctly in the macro.
Once those pages are saved and published we are done. However, you may decide that you don't want your child pages to be accessible from the spine but still visible on the accordion page. This is simple and easy to do, go to each of the content pages you want to hide and click the 2nd checkbox from the top labeled "Hide in Navigation", and then save.
Note: Users will only be able to view information from one accordion entry at a time.
