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 datepickerTime = flatpickr('#datepicker-time', {enableTime: true, onReady() { this.showTimeInput = true }, dateFormat: "d/m/Y H:i", clickOpens: false, allowInput: true, closeOnSelect: false});


var datepickerTimeTrigger = document.querySelector('#datepicker-time-trigger');
datepickerTimeTrigger.addEventListener('click', function() {
    datepickerTime.open();
});
