I'm using the Web Builder contact form in Odoo 18 to create new contacts. The form includes a dropdown to select a state(province), but currently:

• The state dropdown shows every state in the world, regardless of the selected country.
• It's not searchable, so users have to scroll through a long list to find the right state.

I'd like to achieve two things:

1. Filter the state options based on the selected country (only show states that belong to the chosen country).
2. Allow users to type and search within the state dropdown for easier selection.

Is there a way to do this through customization or settings in the form view or website form widget?

Any guidance would be appreciated!
