I have not seen any built in component that does that. You can simulate then same thing by inserting and removing Fields - which is what I suspect this does anyway.
To do this, create a Manager and supply if with a Heading and a number of "collapsible" Fields. Have the Manager just add the Heading as say a focusable LabelField and listen for navigationClick on that Field. If it is clicked and the only Field in the Manager is the Heading, then add all the rest. If it is clicked and there are Fields in the Manager in addition to the Heading, then remove the extra Fields. This will emulate the functionality that you see,
This can be improved by making the header Field a bit sexier with a +/- icon, and also you can make the process more efficient using additional Managers. But the above process should get you going.
Hope this is clear.
