We have some very large infoboxes. They are collapsed within the app but on the mobile site come before any other content. We should consider collapsing on mobile. Or at least allowing parts of them to be collapsed.

I believe the Beta or Experimental mode of the mobile website is already experimenting with this.
@TheDJ In the alpha mode we were hiding the infobox and substituting it with a wikidata generated infobox but that experiment is being phased out. Right now I don't think we have anything like what the apps do.
@Doc James I've created T109703 to track this request. I would appreciate if you chimed in there and expanded your thoughts. Your input would be extremely valuable.
