It is possibile save a HTML page to PDF choosing which fields can be compiled after saving directly from the PDF document?
(I would only use jquery if possible)
Thanks in advance
This is a poorly-asked question (no offense) which is leading to the downvotes I believe, but yes it is possible. Start here. Html2Pdf I allows "creating" a pdf form field, so you'll have to just coordinate that between the client and the server side when telling what you want to render.
The video's in French, but is very helpful regardless.
UPDATE: this SO question also is relevant and has plenty of good information, whether you'd be using PHP or not. Also, after re-reading your "requirements" in your question, you might be able to pull off some wizardry with pdf.js if you're just trying to stay client-side, or a google search for "render pdf from html using javascript" or something to that affect (not being glib or condescending -- sometimes knowing where to start in Google searches is half the battle).
