Streamlining the process of creating a new entity through Autocomplete/Live Components (and maybe Dynamic Forms)

[Seriousedy]

Hello,

I'm basically looking for a solution that could be summarised by this issue: #1890

Searching through the docs and anything else available proved to be less useful than I'd hoped.

The use case that've been giving me trouble is the following:

Using live components and simple regular entity autocomplete, I'd like to be able to create a new entity using the tom select 'create' option. Since my entity requires several other parameters, I'd like to display an additional FormType that should relate to the properties of the newly added option in tom select.

A visual example:
the tom select

the new fields that should appear only

some code samples

->add('azureDomain', EntityType::class, [
                'class' => AzureDomain::class,
                'choice_label' => 'type',
                'autocomplete' => true,
                'attr' => [
                    'data-controller' => 'azure-domain-autocomplete'
                ],
                'tom_select_options' => [
                    'create' => true,
                ],
            ])

$builder->addDependent('newAzureDomain', 'azureDomain', function (DependentField $field, ?AzureDomain $azureDomain) {
            $field->add(AzureDomainType::class, [
                'mapped' => false,
            ]);
        });
