Musescore.org page-edit questions: 1.) drop-down functionality 2.) tutorial drafts: hiding "pre-publication" content

1.) I'd like to confirm that there is currently no ability to insert a drop-down element in Handbook or tutorial pages. I don't see anything in the markdown tips page (https://musescore.org/en/filter/tips), and I don't think I've seen any drop-downs in the Handbook itself, but if they are possible, I'd like to know.

2.) I don't see a way to draft tutorial content on Musescore.org and then "publish" it when it gets in a polished state. Am I right that you can't currently do this, or am I overlooking something?

If it's not available, I'm guessing the advice would be to use a markdown viewer to preview content as it is edited (which wouldn't give you the ability to view images or get the "look and feel" experience, but would be better than nothing). Something like a writer's sandbox or the ability to keep tutorial drafts un-published would be useful.

Thanks.
