Form handling improvement (self-contains and AJAX like)

[SYip]

It would be beneficial for form components to manage their own submission logic internally. This approach offers several advantages:

Enhanced Reusability: Components become self-contained, handling submission and rendering updates independently. This allows for easy reuse across different pages and applications.

Improved Code Organization: Decoupling submission logic from page-level code leads to cleaner, more maintainable codebases, especially when dealing with multiple forms per page.

Support for AJAX-like Behavior: One feature that would greatly enhance Fresh's form handling capabilities is built-in support for AJAX-like behavior. This would allow developers to update forms without full page reloads, creating a smoother and more responsive user experience. Fresh currently supports Partial, however, it changes the url when a form is sumbitted.

This feature would provide a valuable alternative to traditional AJAX, enabling developers to create dynamic and responsive forms within the Fresh framework.

Couldn't you just make a form inside an island that talks to a separate API route?
