[TYPO3-mvc] Expandable items tree - how to make it with Fluid?

I'd say you need a custom viewHelper for this - something like 
"isInRootline". Another approach could be to prepare a rootline array in 
your controller, pass it to the view and use/create a "contains" 
viewHelper or something like that. I currently don't see any other 
approach. I know that there are already some working solutions for menus 
for FLOW3/TYPO3v5 but I don't remember how it's done there in detail - I 
only remember that they also used nested partials. Maybe you want to 
have a look there.
