attach()

void MayaFlux::Portal::Forma::Collapsible::attach	(	Layer &	layer,
		uint32_t	body_id
	)		const

Relate a body element to this collapsible and sync its visibility to the current open state.

This is the only bookkeeping Collapsible does for an attached body - everything else lives in Layer::m_relations, keyed by header_id. That means Portal::Forma::destroy(surface, header_id) tears down every attached body for free, with no Collapsible-specific teardown code.

Parameters

layer	Layer the body element lives on.
body_id	Element id returned from layer.add(...).
