Option to keep sidebar groups collapsed even when viewing a page inside them

[pvaswindas]

Feature Request

It would be great to have an option to keep sidebar groups collapsed by default, even when viewing a page inside one of them, and also allow manual collapsing afterward.

Current Behavior

Currently, when visiting a page within a group, Mintlify automatically expands that group in the sidebar.
Even if "expanded": false and "interaction": { "drilldown": false } are set in docs.json, the group still opens automatically and cannot be manually collapsed again.

Desired Behavior

• Groups should stay collapsed by default, regardless of the active page.
• Users should be able to manually expand or collapse groups in the sidebar.

Use Case

In large documentation sites — especially with extensive API Reference sections — this would help keep the sidebar organized and easier to navigate.
For example, I have several API categories under the API Reference section, and it becomes cluttered when all groups expand automatically.

Example docs.json snippet

{
  "navigation": [
    {
      "group": "API Reference",
      "expanded": false,
      "pages": [
        {
          "group": "Accounts API",
          "expanded": false,
          "interaction": { "drilldown": false },
          "pages": ["api/accounts/get", "api/accounts/post"]
        },
        {
          "group": "Transactions API",
          "expanded": false,
          "interaction": { "drilldown": false },
          "pages": ["api/transactions/get", "api/transactions/post"]
        }
      ]
    }
  ]
}

Mintlify has been amazing to use so far, and this feature would really help make large docs even more user-friendly.
