The following preprocess function will give you unique classes on the body tag for each Group content type (from the Group module). It adds two classes, one that includes the Group type that the content is in as well as the Group content type (e.g. group-content--client-group--node-page); and one with just the Group content type (e.g. group-content--node-page).
Place this code in your theme's .…

The following template suggestion (placed in your theme's .theme file) will give you field template suggestions per entity type, e.g. field--node.html.twig, field--group.html.twig, field--media.html.twig, etc. I wanted to theme all fields in Groups the same way, and didn't want to have to create field templates for each group type, which was the least granular template suggestion available.
This…

Someone contacted me asking for help with the following:
I am trying to look at the particular user profile, and below that profile contains a stream of content nodes which I will be able to see only content created by that particular user in group that I am a member of.
Example. If A is a user who created 2 Group’s and has added me to one of…

I wanted to change the format of the comment submitted timestamp on my blog, and figured it could be done in Twig - but nope. There's an active issue on Drupal.org to allow the format to be changed in the UI, but until that's done, you need to use a theme preprocess function.
function THEMENAME_preprocess_comment(&$variables) { $date_formatter = \Drupal::service('date.formatter…

This is slightly adapted from presentation notes, so it's a bit sketchy. It's more of an outline of requirements, rather than code samples. I may add those later. Also, note that I've only covered two scenarios: a dropdown menu, and a menu that covers the entire screen when opened (modal dialog). There may be different considerations for other styles.
Mobile menu: usually the site's main menu,…

I previously wrote about how to create a View of content from a Group that a user is a member of. For another site, I have to show a list of other members in the same group on user profiles. Another common use case might be showing a logged-in user a list of other members in his/her group(s).
You can do this two ways:
Create a View of Group Content of type [Group name]: Group membership
or…

Drupal has gotten so much more powerful and easy to work with, but there are still a few things that are missing that seem like they should be a given. Such as, the ability to format certain Views exposed filters, like node titles or Group names, as dropdown select lists rather than an empty textfield that requires the user to know what the possible options might be instead of presenting them.…

The Group module is a powerful one I turn to often when a site has a requirement for groups of users who should have specific permissions, access to edit or view specific content, etc.
A common requirement is to show a list of content belonging to the Group(s) a user is member of, using Views. That isn't as straightforward as it seems. I recently had to do this and struggled a bit, so thought…

I've worked on several sites recently where the site search form is hidden by default and displayed by activating a button. This pattern caused me a bit of confusion about where to put the role="search" attribute, which is important for accessibility.
According to the W3C specification the search role is:
A landmark region that contains a collection of items and objects that, as a whole, combine…
