Can I do this with Avo?

Hey guys! Could you comment on how they solved some problems that it was not possible to solve with all the facilities that Avo offers, for example:

1. With a Custom Tool, can I create a completely customized MVC, as if it were an application without Avo?;
2. How do I create two master-detail (countries-cities) type dropdowns
3. Where you could customize a mask for a given field, for example, a numerical field 12345-678, or 123.456.789-00; 4) If I needed to move the user's icon to the top, how could I customize it?

1. You can still use the MVC pattern within Avo without using a resource tool. You write regular Rails code. You have to have a few things in mind.

# controllers inherit Avo's application controller
class Avo::CatsController < Avo::ApplicationController
end

# Declare the routes in your routes.rb file within Avo's scope
Rails.application.routes.draw do
  # your other routes
  mount Avo::Engine, at: Avo.configuration.root_path
end

# here👇
if defined? ::Avo
  Avo::Engine.routes.draw do
    resources :cats
  end
end

2. You can add that with a bit of custom JS. We actually have that implemented in the demo app.

3. That requires some JS, as far as I know. HTML doesn't support that by default, right? So a custom field is what you're looking for.

4. To the top where? You can open the dev tools, check what partial is rendered and where, duplicate that partial in your app, and apply your changes.
   Rails will use your file to display before using ours, and you'll have ownership of that file (future updates to that file will not be applied as long as you override that file).

Thanks again, Adrian who never sleeps. I don't know how you manage to respond in all groups and networks, with answers that are not generic, and still make Avo better and better.

Thanks for the kind words Dailson. Yeah, it's not easy. It was a wild day and only now reached to this request.
