bug(Angular Material Docs): Broken version selector in docs

[em843]

Is this a regression?

• Yes, this behavior used to work in the previous version

The previous version in which this bug was not present was

18, I think.

Description

The selector used to toggle the version of documentation is not working, so you cannot access documentation from previous versions of Angular Material from the current docs.

If there is a better place to submit this issue, please let me know.

Reproduction

This is a bug with Angular Material's website that hosts its documentation, not a component, so I cannot reproduce it via code.

Expected Behavior

I expected the selector to expand a list of options to choose from

Actual Behavior

The selector does not expand a list of options but occasionally flashes part of the menu.

Environment

• Angular: 19.2.12
• CDK/Material: N/A
• Browser(s): Chrome
• Operating System (e.g. Windows, macOS, Ubuntu): macOS

Is there any work around this? etc direct url for accessing historical versions before this bug been fixed?

[crisbeto]

We're working on fixing it. Accessing the old URLs directly still works.

Where could I find the old urls?

Many thanks.

The pattern is v<version>.material.angular.dev. For example: https://v18.material.angular.dev/
