How to use Select2 with Reactjs?

Answer 1

Simple wrapper.

Add select2 js + css on index.html, write wrapper over select input

function renderOptions(option_items) {
    if(option_items) {
        return Object.entries(option_items).map(function (item) {
            return {item[1]}
        })
    }
}

class Select2Input extends Component {

    constructor(props) {
        super(props)
        this.ref_input = React.createRef()
    }

    /**
    * Add select2 bind and send onChange manually
    */
    componentDidMount() {
        const self = this

        $(self.ref_input.current).select2({
            tags: true,
        }).on('change', function(event) {
            var value = $(event.currentTarget).val()
            if(self.props.multiple === true) {
                value = List(value)
            }
            self.props.onChange(self.props.name, value)
        })
    }

    /**
    * Emit change event for reload select2 if options has change
    */
    componentDidUpdate(prevProps) {
        if(prevProps.option_items !== this.props.option_items) {
            $(this.ref_input.current).change()
        }
    }

    render() {
        return
