Like most output in Drupal, Views relies on Twig templates for a significant amount of its rendering. In this tutorial we'll identify where you can find the default Views templates within your file system, what the common templates are for, and how to name your templates so that they are applied to specific views.
By the end of this tutorial, you should be able to:
- Identify where to find default views templates
- Understand which templates apply to what part of a view
- Get a sense of the template suggestions and how to use them to limit where your custom templates are applied
- Identify a view's machine name
- Identify a display's machine name
- Identify a field's machine name
One of the challenges that comes with Layout Builder is increased complexity of front-end development. Layout Builder offers site administrators increased flexibility regarding the placement and use of fields and blocks; a theme developer needs to account for this. Depending on how Layout Builder is used, this could mean a small number of new combinations, or virtually infinite combinations. Therefore, predicting and theming all of these combinations becomes a difficult but necessary task in order to ensure maintainability and overall design consistency.
In this tutorial we'll look at some things we've found helpful to consider when theming Layout Builder including:
- Design, and theme, atomic components
- Limit the number of possible combinations of fields by using entity view modes
- Handle edge cases
By the end of this tutorial you should have a better understanding of how using Layout Builder can impact theme development, and how to account for it.
This video was part of a series of presentations produced in anticipation of Drupal 8's official release. For information about multilingual sites based on official releases of Drupal 8, take a look at our Multilingual sites topic.

[# endcard #]
This presentation outlines some of the major changes to the Drupal core multilingual system. A lot of features that were in contributed modules have been rolled into core, and a number of existing multilingual features have been greatly improved. There are a lot of cool new things to get up to speed with. In this video, we'll review:
- New and obsolete modules
- UI changes
- Developer changes
After watching this presentation you should have a better understanding of the things you'll need to learn to get up to speed with the new multilingual features in Drupal 8, including things to watch for on the module development and theming sides.

GuideWe recommend planning ahead when using Layout Builder, documenting how you intend to use Layout Builder for your specific use-case, and then doing your best to stick to it. One approach that we've found works well for sites that need a maximum amount of flexibility (and have the resources to do the upfront planning and theming required) is using entity view modes.
This approach is similar in concept to component based design systems, where you do the initial work of creating a set of components that all work well together up-front, and then allow them to be mixed and matched in whatever way is necessary.
In this tutorial we'll:
- Create new view modes for the Basic Page content type representing the different components.
- Use the ctools blocks module to allow displaying an entity as a block and choosing which view mode to use when rendering the entity.
- Provide custom HTML and CSS styling for the new components.
By the end of this tutorial you'll know how to use Layout Builder in combination with entity view modes.

What's New in Drupal 8
CourseLike many things in Drupal, there are multiple ways to solve the same problem when using Layout Builder. The Layout Builder system is very flexible. In order to be successful when using it, it helps to plan ahead and think through your specific use-case. Picking a pattern, and sticking to it, will help ensure your configuration is more maintainable, and easier for others to understand. While there's nothing to prevent you from mixing and matching, in our experience we've found it's helpful to at least set some ground rules.
In this tutorial we'll outline 3 different patterns to use with Layout Builder, and the pros and cons of each. We'll include:
- Using content fields in scenarios where a few pages use Layout Builder, but the majority of the site's layout is done via the theme and is generally not configurable by editors.
- Using a blocks-based approach to layouts for scenarios where you want to use Layout Builder instead of the traditional blocks and regions approach and allow editors to make changes via the UI.
- And finally, using an Entity view modes approach for sites that rely heavily on Layout Builder and contain lots of interrelated content types with complex layout requirements.
By the end of this tutorial you should have a better understanding of how to approach using Layout Builder for your specific use-case, and the advantages and disadvantages of different common patterns.

Drupal media entities are fieldable entities, which means that you can add any custom fields you want to your Media types. These fields can be used for collecting additional metadata about a resource, categorizing and organizing resources so they're easier to find in a large media library, or for displaying information like a photo credit or transcript for a video. The possibilities are endless once you know how to add, and optionally display, fields in Drupal.
Some example use cases for adding fields to Media types:
- Collect, and display, a credit to go along with a photo. This could also be a date, a location, or any other metadata.
- Store resource width and height dimensions as custom fields so they can be referenced by display logic in the theme layer.
- Use Taxonomy reference fields to add tags or categories to help keep a large library organized.
In this tutorial we'll:
- Learn how to add fields to a Media type
- Verify our new custom field is working
By the end of this tutorial you'll know how to add custom fields to any Media type.
Now that we understand what templates are and how we can use them, let's override some templates! In this tutorial we'll copy the views wrapper template to our theme and override it so that we can customize the markup for the Baseball Players view. Then we'll modify the template so that our view's pager appears both above and below our table of players.

Planning for a migration is essential. In our collective experience we've never once seen someone sit down and execute a migration flawlessly on their first attempt. Migrations involve preparing and analyzing your source data, building a new website that data can be migrated into, and lots of testing, rolling back, and testing again, in order to get everything right. By the end of this tutorial you should be ready to start planning for your own Drupal migration project, and have a better understanding of the challenges of migrating from one system to another.
Layout Builder is one of many different approaches to handling editorial layouts in Drupal. Now that it's stable, and part of Drupal core, we expect to see it become the dominant approach over time. However, as with most things in Drupal, there are multiple ways to solve the problem of creating component based flexible layouts that can be administered via the user interface.
It's a good idea to understand the different approaches and know what's available.
When it comes to component based design and ability to construct flexible layouts, it is important to understand the benefits and risks of the most popular techniques: Paragraphs, Bricks, entities and view modes, and Layout Builder. Understanding which approach fits the needs of your project best can be critical for its success in the future.
In this tutorial we'll look at some common approaches to administering layouts in a way that gives content editors controls including:
- Drupal core's Layout Builder
- Using core's entity reference fields and view modes
- The contributed Paragraphs module
- The contributed Bricks module
By the end of this tutorial you should have a broad overview of the different popular approaches to creating editor-controlled layouts.
Before you begin a Drupal 6 or 7 (source) to Drupal 9 or 10 (destination) migration there are a number of things you should consider. Taking the time to plan your migration will help to ensure that you're successful. In this tutorial we'll take a high-level look at:
- Evaluating your existing Drupal 6/7 site for migration feasibility
- Preparing your source Drupal 6/7 site for a migration
- Preparing the destination Drupal site you're migrating to
By the end of this tutorial you should be ready to start assessing the feasibility of performing a successful migration, and begin making a migration plan.
