Collapsible overlay for google maps

Hi guys,

This solution will probably lead to a third party plugin which I realise you can not offer support for, however if you have any suggestions for a suitable plugin to use, that would be awesome.

I’m trying to achieve a collapsible overlay for google maps that allows mobile users to continue scrolling down if they click the overlay which would cover the map. A perfect example of this is shown at the bottom of the page here: http://hip-chalets.co.uk/
I realise you can prevent enfold’s map to pan however this is undesirable for me.

I would be glad to hear any comments from the community too.

Thanks in advance.

James
