UI Improvement: Table of Contents not filtered by selected language

[ravixalgorithm]

While exploring the ADK documentation, I noticed a small UI inconsistency in the “Build a multi-tool agent” and some other pages.

When a specific language (e.g., Python, TypeScript, or Java) is selected, the Table of Contents still displays entries for all languages instead of showing only the sections relevant to the selected language.

This can be slightly confusing for readers, especially beginners, as the ToC suggests content that isn’t currently visible or applicable.

Expected Behavior

The Table of Contents should dynamically update to show only the sections corresponding to the currently selected language.

Actual Behavior

The Table of Contents includes entries for all languages regardless of the selected language tab.

Why this matters

• Improves clarity and focus while reading docs
• Reduces cognitive load for new users
• Aligns ToC behavior with the selected language context

Proposed Solution (Optional)

Conditionally render or filter the Table of Contents based on the active language selection.

Additional Context

This seems like a minor UI enhancement, but it could significantly improve the documentation experience.
