To add more models just declare the urlids on
var models =
And add more iframes as
api-frame0, api-frame1, api-frame2...
You'll can hide all info frames using jQuery and show them when reached annotation .
To use on mobile just change the class of
"col-xs-12 col-sm-8" and
"col-xs-12 col-sm-4". It's fully responsive. Use "back to top" affix button if needed. I didn't try "leaflet-control-window" with Sketchfab i-frame.
