🐛 Bug: Sidebar sub-navigation does not auto-collapse

[TarunyaProgrammer]

Describe the bug

The documentation sidebar allows multiple sub-navigation sections to remain expanded at the same time. When a new section is opened, the previously expanded section stays open.

This results in a cluttered sidebar and makes navigation harder, especially as more sections are expanded.

This behavior differs from the commonly expected accordion-style navigation used in documentation sidebars, where only one section is expanded at a time.

Steps To Reproduce

1. Open any documentation page.
2. Expand a sidebar section (e.g. Get Started).
3. Expand another sidebar section (e.g. Guides).
4. Observe that the previously expanded section remains open.

Expected Behavior

When a sidebar sub-navigation section is expanded, any previously expanded section should automatically collapse.
Only one sidebar section should be expanded at a time.

Actual Behaviour

Multiple sidebar sections can remain expanded simultaneously.

Why this matters

• Reduces visual clutter in the sidebar
• Improves scanability and navigation speed
• Aligns with common accordion navigation patterns used in docs sites
• Simplifies focus for keyboard and screen reader users

Additional Notes

This appears to be a UI state-management issue where expanded sections are handled independently rather than as a single active section.

Hello @Utkarsh-123github
I’ve opened PR #2198 which implements this behavior.
Happy to adjust the approach if you’d prefer a different interaction pattern.
