Thanks.
What we really need is for the full page to be picked up, whereas the example you link to (done with javascript off) is just picking up but one part of the overall page (solely the content of but one of the toggles) - we'd want the whole page with all toggles included.
What we've done is setup our pages using Header styles such that printfriendly uses them to create bookmarks in the pdf files - so each toggle creates a 'chapter' in the overall pdf. It's worked nicely on some pages, but not all.
Hope that helps in what you're doing with the update. Thanks for the support :)
