Tree nav isn't accessible on mobile #3323
Description
On desktop, the tree nav (circled in red) provides a critical way to navigate the docs:
On mobile, the tree nav is hidden, and the hamburger menu only brings up (the mobile version of) the top nav, not left-side tree nav. There's no way to access the tree nav anymore.
On Redocly's official site, the hamburger menu defaults to tree nav with a "< Main menu / Docs" link that takes you to a mobile version of the top nav:
I suspect that what happened is Redocly changed to how/where the default page layout shows the tree nav—they moved it so the way you access it is through the hamburger menu, but that's lost on us because we have a totally custom hamburger menu.
