ReactJs select, no value displayed

I'm learing reactJs and trying to use react-select.

html:

<div class="col-md-2">
            <div class="well">
                <h1>h1</h1>
                <div id="countriesSelect"></div>
                <div id="exp"></div>
                <!-- Scripts -->
                <script src="/js/bundle.js"></script>
            </div>
</div>

app.js:

var React = require('react');
var ReactDOM = require('react-dom');
var Select = require('react-select');

const getOptions = (input) => {
    return fetch('//api.local/api/countries') //users/${input}.json
        .then((response) => {
            return response.json();
        }).then((json) => {

            var data = [];
            json['data'].forEach(function(item) {
                data.push({value:item.attributes.slug,label:item.attributes.title})
            });
            return { options: data };
        });
}

ReactDOM.render(
    <Select.Async
        name="countries"
        loadOptions={getOptions}
    />,
    document.getElementById('countriesSelect')
);


var options = [
    { value: 'one', label: 'One' },
    { value: 'two', label: 'Two' }
];

ReactDOM.render(
    <Select
        name="form-field-name"
        label
        options={options}
    />,
    document.getElementById('exp')
);

app.js to bundle.js -> browserify -t [ babelify ] public/js/app.js -o public/js/bundle.js

Result:

enter image description here

The problem - when trying to select someting from dropdown, no value shown in select. Always see the Select... label.

it looks like you are missing the value prop on the Select component and need an onChange prop as well to handle when you click a dropdown option. I highly suggest making your own select component that wraps the react-select library that way you can pass custom props and create custom functions that are used with the react-select library.

var value; // initialize the value variable

function updateValue(selectVal) { value = selectVal // update value variable to new value }

<Select name="form-field-name" label value=value // set value to value onChange= updateValue options={options} />

that should get you where you need to be
