[Neos] Render Subpage Content

[Florian Biermaier]

Hello all, 
i curently work on a OnePage Neos Site and have the Problem to render the Subpage conent. I already found the TS2 code from Christian Müller and it looks as it does exactly that what i need. But how must i add this in my flow template?

TS2 Code:
SubContent = TYPO3.TypoScript:Collection {
						collection = ${q(node).children('[instanceof TYPO3.Neos:Document]')}
						itemRenderer = TYPO3.Neos:ContentCollection {
            				nodePath = 'main'
        				}

						itemName = 'node'

			}
