Seconding this issue. A portfolio/project page takes time to create and curate. Having it go live as soon as it's created is unacceptable. The solution linked above by Jo_G does not work for this use case. I don't want to password protect my entire Portfolio collection, just the 1 new item that I'm adding to the existing collection.
Currently it looks like it's impossible to hide / password protect an individual collection item without resorting to CSS hacks.

I've run into a bit of an issue with hiding individual collection pages in Squarespace 7.1. Normally, by clicking on the settings for a page, you are able to enable or disable that page. However with the new system of "Portfolio Collections" that page disable option does not exist for individual portfolio project pages. I may be mistaken, but as far as I can tell, there is no way to hide these pages (screenshots attached for reference). 
This is incredibly troubling as you cannot create drafts of projects, nor if you are duplicating other projects, they will be live with duplicate content until you fix it. 
I was thinking possibly that you could move collection pages to other collection pages(in the way you can move products from shop to shop), so in essence you could pre-build the portfolio page on a hidden portfolio collection and move it to the live portfolio collection, but there doesn't seem to be a way to do this either.
Any advice on how I could make hidden pages in the existing Portfolio Collection system or is this just a fault in the new version?

Yes. It's a bit arbitrary why portfolio's in 7.1 can't be password protected yet pages can. A entirely plausible usage-case is you have a body of work, not just a single project, that requires it be hidden.
This ought to be addressed.

This is super frustrating! like mentioned above, building a project page takes even longer than a normal page to build and should be hidden until it is ready to be live. I really hope this can be addressed soon Sqaurespace and at the meantime we're all "locked" in this painful experience. what am I suppose to do at the meantime? how come older versions like 7.0 has it while I don't? and how do I switch to this older version if i wish without damaging everything I built?
