[Closed] CA on Render Element Rollout?

I’ve successfully added a Custom Attribute for a render element but I don’t get an additional rollout from my CA, is it possible to add these???

Persistent Global RenderElementCA = attributes RenderElement
(
	parameters main rollout:RL_RenderElement
	(
		addbyMe type:#boolean
		ID type:#string 
	)
	Rollout RL_RenderElement "Render Element"
	(
		label lbl_hyd "Render Element Added by me"
	)
	
	
)

re = maxOps.GetCurRenderElementMgr()
theElement = re.getrenderElement 0

custAttributes.add theElement RenderElementCA
