I have custom html code with form, and want to use JSOM to create new item.
I want to have completely blank page, but with SharePoint context. How do You usually do it? As I understand I can create minimal.master in Design manager, then create Page layout inherited from this minimal.master, then add page in "Pages" (I have Publishing sites). But this page contains a lot of data- quicklaunch, ribbon.. Of course I can hide these all with CSS, but not sure it is best practice.
How do You use custom html inside SharePoint - create master pages and then delete all unnecessary placeholders? I've read that it could break sync between *.html and *.master files. Or delete them on Page Layout level?.. I also don't understand why I can inherit from "Article", "Welcome Page", etc. types only. I need 'Empty' one..
