ObjectSelect with optgroup support

[sparrowek]

It would be nice to be able to have an ObjectSelect that groups elements using optgroup html tag.

@gianarb how would you feel about an option where the optgroup is defined by a second field of the same table? I.e:

Items
id | title | group
1 | Foo | foo
2 | FooFoo | foo
3 | Bar | bar

And the options then would look similar to this:

$this->add([
    'type'    => 'DoctrineModule\Form\Element\ObjectSelect',
    'name'    => 'type',
    'options' => [
        'label'              => 'Items',
        'object_manager'     => $objectManager,
        'target_class'       => 'Entity\Item',
        'display_empty_item' => true,
        'empty_item_label'   => '--- (required) choose an item ---',
        'property' => 'title',
        'optgroup_property' => 'group'
    ]
]);

And then stuff being rendered accordingly?

I'll be working this within the current project im working on and could easily do it as a proper doctrineModule feature as well. The thing is that this is a quite "local solution".

It may be cleaner to have a separate table for optgroups and then connect the tables (DB wise).

thoughts?

Hi! In my opinion this is a good idea!

[manuakasam]

Alright, I'll give this a shot though then within the coming weeks.

[gianarb]

Thanks! :) I wait your PR.. Thanks for this feature

Thanks @manuakasam. I really like this feature. Did you think of a label generator for the optgroups? I would do a PR myself but i'm not that familiar with the doctrine code yet.

[manuakasam]

@xelax90 that wouldn't go hand in hand with the current implementation. As you do need an identifier within the database for the current implementation to work. And in this case a label_generator (for the optgroup-title) would not be required.

The options itself are able to generate their label as usual.

Closing for - obviously - lack of interest/relevance.
