Auto select first item if there is only 1 option

[susanu]

As the title says, for fields like: relationship, select2, select and so on, add an option to auto select the first item in the list if the list contains only 1 item.

Based on the knowledge sources provided, there doesn't seem to be a built-in option in Backpack to automatically select the first item if there is only one option in select fields like relationship, select2, or select. However, I can provide some information on related functionality and potential workarounds.

1. For select fields, you can set a default value using the default attribute. This is mentioned in the Github issue about select2_from_ajax, where it's stated that the default attribute is available for all field types.

2. For relationship fields, you can use the default attribute as well. This is demonstrated in an example from the Github issue about default selected items:

$this->crud->addField([
   'label' => "Category",
   'type' => 'select',
   'name' => 'category_id',
   'entity' => 'category',
   'attribute' => 'name',
   'model' => "App\Models\Tag",
   'default' => '25'
]);

3. If you want to implement custom behavior, you might need to use JavaScript to check the number of options and select the first one if there's only one. However, this would require custom development and is not a built-in feature of Backpack.

4. It's worth noting that Backpack has been working on improving the user experience for select fields. For instance, they've implemented autofocus functionality for select2 fields, as mentioned in the Github issue about Select2 Autofocus Option.

If you need this specific functionality of auto-selecting the first (and only) option, you might need to implement a custom solution or request this feature from the Backpack team. The current documentation and issues don't mention a built-in way to achieve this exact behavior.
