About an enhancement regarding the tags feature suggestion

This project is truly impressive and helpful. I'd like to request an enhancement regarding the tags feature.

1.Tag Categorization: Organize tags into categories. For example: OS-related tags[windows11],[linux]; language-related tags[js],[go].

2.Enhanced Tag Search in the Interface: On the search interface, allow users to select multiple tags via a dropdown menu, rather than having to type them manually.

3.Tag Selection in Create Question : On the Create Question, it would also be very helpful if tags could be selected via a dropdown menu.

Thank you for considering this suggestion.

This is my first time submitting an issue. If I have said anything inappropriate, please forgive me.

The request covers tag categorization, multi-tag selection in the search interface, and tag selection on Create Question. Start by tracing the tag flows in those two interfaces and identify how tags are currently stored and selected. Done would require an agreed scope and all requested tag interactions working consistently.
