Enhancement: Create, Edit and Details Modal from Flask Admin

[hasansezertasan]

Is your feature request related to a problem? Please describe.
Navigation is neat but I need to be able to create, edit and view the details of a record without navigating to another page.

Describe the solution you'd like
Flask Admin already had this feature builtin, since I'm migrating from it, It'll be great to have. It also speeds things up and offers great user experience.

Describe alternatives you've considered
Flask Admin has it builtin.

Additional context
I'm currently investigating the source code to figure out how can I make it happen. Is it cool to open a PR with no finished code and mark it as a draft to get help from you?
