select2 not working on v4 alpha 2

[JustDylan23]

There is no input box for me to type in that gives autocompletion.

The documentation says that select2 is integrated with sonata admin and that it is enabled on every select without doing anything

->add('owner', ModelType::class, [
    'property' => 'username',
])

I honestly have no clue why it isn't showing up

I have both the admin-bundle and the doctrine-orm-bunde on version 4.0.0-alpha-2 currently.

as far as I am aware it should look something like this

Isnt the ModelAutocompleteType made for this ?

[JustDylan23]

ModelAutocompleteType works by calling an endpoint, there should be a client side equivalent of this, right?

[JustDylan23]

In one of our projects at work some of the model type inputs have search boxes and others dont. I am really not sure what the deciding factor is to whether you get a searchbox or not.

There is search box only if there is enough choices. I don't know how many but I have noticed this in 3.* and haven't even tested 4

Based on https://github.com/sonata-project/SonataAdminBundle/blob/82afd8a37ef233a9b00d5751f679f9810de05a57/src/Resources/public/Admin.js#L104-L132

Looks like it shows the search box when there are more than 10 results and you can modify it with the data-sonata-select2-maximumSelectionSize attribute like https://symfony.com/doc/current/bundles/SonataAdminBundle/cookbook/recipe_select2.html#disable-select2-on-some-form-elements

It would be pretty nice to have this documented somewhere, can somebody edit the documentation?
