Support auto collapsing menu (left side catalog) on published docs

Please see: https://placewise.eu.apidog.com (it’s WIP, we’re still testing the capabilities)

As you can see, the API organization is pretty complex which may be overwhelming and we’ve got accustomed to auto-collapsable nav menu.

It would be very nice if the menu could be configured to auto collapse like here (the docs are implemented with docusaurus).

Thank you for the feedback, this feature is already in our roadmap and we will support setting the default expand/collapse state for each directory in the future.
