Is it possible to export a single muse page (say a products page) into an existing site (not created with muse)? How would I go about this?
Yes, I think you can.
You have to export the Muse-Site as HTML and upload evrything (js, css, html, pics, folder) to root (existing page) and link the single site from the existing page. Use a external ftp-program e.g. Filezilla or Dreamweaver's FTP-client. But be carefull: dont override existing files (same name, same folders). Or use a single product page as a landing page: then you got the option to run it in a subdomain where you can upload the whole exported HTML files from muse.
Hope that will be helpfull
Sorry for the delayed response.
I'm still unsure how this thing goes. So currently my muse file has a main Products page and individual product pages.
I will be appending those pages to a separate non-Muse site. Does it matter that the main Products page is currently defaulted to index.html in Muse? Or will it be fixed to products.html when I upload the files to the non-Muse site.
