Instance Method Details

#child_element(tag_name, stimulus_controllers: nil, stimulus_targets: nil, stimulus_actions: nil, stimulus_outlets: nil, stimulus_values: nil, stimulus_params: nil, stimulus_classes: nil, stimulus_controller: nil, stimulus_target: nil, stimulus_action: nil, stimulus_outlet: nil, stimulus_value: nil, stimulus_param: nil, stimulus_class: nil, **options, &block) ⇒ Object

Explicit kwargs (14 of them, 1 plural + 1 singular per primitive) are the public API — keep them so call-sites get typo-checking and IDE support. The body is registry-driven via ‘Stimulus::PRIMITIVES`.
