I have a table category it has a self relation to have belongs_to simply to be able to create subcategories and assign them to previously created categories and now i need to be able to either assign the new category to another (super) category or to assign it to none.
my model is :
public $belongsTo = [
'category' => ['plugin\pdf\models\Category']
];

This is found in the documents under backend -> forms. Look for the relation
under widget fields. The option you is called emptyOption
and it will be added in your fields.yaml
file.
You would add the emptyOption
like so to model's fields.yaml.
field:
label: Field Label
nameFrom: name
descriptionFrom: description
span: auto
type: relation
emptyOption: None
