Webpage auto lengthen with accordions and popups

[Acorn]

Thanks Acorn,
I originally started to attempt it by editing the published files. It sort of worked but troubleshooting was near impossible. I had wanted multiple drop downs per page, so I realised quickly that it would become too crazy and hard to recreate consistently (everything is different sizes and content updates would require code editing). I briefly experimented with cloning on layers and used anchors. it too sort of worked, but was not smooth and different devices had different levels of roughness.

It seems like a simple action, especially since Xara has the push function already, but I can't find the answer.

Do you know if there is anyway objects on popup layers can push objects on the index or base layer? This could give the illusion of a drop down/accordion.

Repelling only works with text and it is not dynamic.
