by Lee Rowlands /

On a recent Drupal 8 client project our client was building listing pages using views exposed filters and adding these to the menu.

Making Drupal 8 datetime widgets use human formats

by Lee Rowlands /

Drupal 8 includes a datetime field type and widget out of the box.

The widget uses the HTML5 date element on supported browsers, providing a polyfill to a text field with jQuery UI's datepicker for browsers that don't yet support HTML5 date inputs.

However - HTML5 date formats always work in ISO8601 format - ie YYYY-MM-DD - which isn't very user-friendly for those using Firefox and Internet Explorer.
