CategoryPickerTrait
Company category picker with two uses.
- categoryPicker(): repeated selection in a Multiplier (reference categories, many-to-many).
- categoryParentPicker(): single parent-category field (self-reference; excludes the edited category and its whole subtree).
The label is the translated name in the current language. Suggest plus modal with the show grid
:Admin:Company:Category. Requires $this->categoryManager.
