This is a followup to my post "Print formatted date with correct timezone from datetime or daterange field in node and Views templates - Drupal 8".
That post deals with core Drupal Date and Daterange fields. Recently I've been working on a site with events which use a Smart Date field. The Smart Date module offers many features that core Drupal date fields don't, such as recurrence.
Raw Smart…

Anyone who has read this blog before knows that I love the Drupal Group module. It has a companion module, Entity Group Field (not yet stable), which makes it even more useful. This adds a field to entities which allows you to add them to groups on their edit form, rather than having to go separately to the group to add them.
Here's how to print the rendered value of that field in node.html.twig…

Recently, I was creating an event registration Webform. I created a custom composite field with the fields needed for each registrant: first name, last name, and a set of three radio options for their organization status: member, non-member, membership fee included in event registration. Each status has a different registration fee.
I then wanted to create a computed Twig field that would…

I'm working on a website which has icons on file upload links, like so:
This works for people who can see the icons, but what about those who can't? Accessibility means giving all users an equivalent experience, regardless of how they're accessing the site.
If the icons were inline images, we could add alt text with the filetype. However, in this case, they're background images.
So, we want to…

Data attributes on HTML elements can be very handy for targeting certain elements with CSS and/or Javascript.
Let's say, for example, we have a site with a menu whose links have a different background colour depending on what category they belong to, cats or dogs. The HTML might look like this:
<ul class="menu"> <li class="menu-item"> <a…

I've been working on a website with the requirement to truncate certain text fields—display the first several words of the text, with a "show more" link which on click, expands the rest of the text. I had to dig a bit into the Twig documentation to figure it out, but it's easily done with Twig filters and a bit of JavaScript.
(Note that this method will strip any HTML in the text fields. It…
