How can show expand and collapse handles be shown in the Children Display’ Macro

How can I show expand and collapse handles on the Children Display’ Macro

or is there a better macro to show this?

I would look into using the page tree macro. It shows you a page tree that is configurable. You can get all the child pages and drill down into them with expand/collapse.
