// This shows how to override a Form.io component by extending it and creating your own methods.
import SelectComponent from 'formiojs/components/select/Select';
import Components from 'formiojs/components/Components';
export default class CustomSelect extends SelectComponent {
  constructor(component, options, data) {
    // Force all selects to use the html5 widget.
    component.widget = 'html5';
    super(component, options, data);
  }
}

// Override the 'select' component to use our custom class instead.
Components.setComponent('select', CustomSelect);
