We've created a lightweight, extensible, dependency-free datepicker based on <a href="https://flatpickr.js.org/" target="_blank">flatpickr</a>.

```html
<script src="[path-to-volta]/js/addons/volta-flatpickr.js"></script>
<link href="[path-to-volta]/dist/css/addons/volta-flatpickr.min.css">
```
Set the following at the end of the <code>body</code>:

```javascript
var datepicker = flatpickr('#datepicker', {altInput: true, altFormat: "F j, Y", dateFormat: "d/m/Y", clickOpens: false, allowInput: true, closeOnSelect: false});

var datepickerTrigger = document.querySelector('#datepicker-trigger');
datepickerTrigger.addEventListener('click', function() {
    datepicker.open();
});
```
<code>altInput: true, altFormat: "F j, Y"</code> allows you to display an alternative date format to the user (see <strong>Notes</strong> for formats). <br />
<code>dateFormat: "d/m/Y"</code> will be used as the value of the input, but hidden to the user.
