App.js error when expanded => true on ChoiceField

[Dumorya]

Describe the bug When 'expanded' => true, the following error appears in the console:

app.js:2 Uncaught TypeError: Cannot read properties of undefined (reading 'length') at e.S (app.js:2) at e.value (app.js:2) at app.js:2 at NodeList.forEach () at Object.createAutoCompleteFields (app.js:2) at HTMLDocument. (app.js:2)

If 'expanded' => false, no error is showing up.

To Reproduce EasyAdmin version used: 3.5.17

Set a ChoiceField like this one in a CrudController:

ChoiceField::new('bottling')->hideOnIndex() ->allowMultipleChoices(false) ->setFormTypeOptions([ 'expanded' => true, 'multiple' => false, 'placeholder' => false ]) ->setChoices([ 'Yes' => true, 'No' => false ]),

Please go on the admin form page of this Crud, and check the console.

            ])
        ;

Quick and ugly workaround for AssociationField, Just duplicate vendor/easycorp/easyadmin-bundle/src/Field/AssociationField.php to src/Admin\Field/ExpandedAssociationField.php

        yield ExpandedAssociationField::new('associationField') 
            ->setFormTypeOptions([
                'expanded'  => true,
                'class'   => UsedEntity::class, // Need to specify the entity!
            ]);

@Dumorya, it's works with ChoiceFIeld too but you need to specify the choices in setFormTypeOptions() method and not in setChoices

 yield ExpandedChoiceField::new('uais')->onlyOnForms()
         //  ->setChoices($choices) // do not work
            ->setFormTypeOptions([
               'placeholder'=> false,
                'choices'   => $choices, // <= set choices here
                'expanded'  => true,
            ])
        ;
```The

The javascript of the page executes well.

Just adding ->setCustomOption('widget', null) will resolve this issue👍
