User-Friendly Filter System for Starlette-Admin

[nimaxin]

I watched the starlette admin demo, and it looks very close to what I need—but the filtering system is still an issue.

The current filter system in starlette admin is more developer-oriented, relying on SQL-based operations like AND, OR, and CONTAINS. However, most admins are not developers so this approach can confuse them.

I suggest implementing a django admin-style filter system, which is more user-friendly and accessible. Instead of requiring SQL knowledge, it provides simple UI elements like dropdowns, checkboxes, and date pickers—allowing non-technical users to filter data easily.

This change would make starlette-admin a much more practical choice for a broader range of users.

Would love to hear your thoughts on this!

Indeed, that would be a great additional feature to have. Although I don't have enough time to prioritize it at the moment, I'm open to PR.
