By default, individual forms in Drupal are not output using Twig template files. It's possible to associate a form with a Twig template file by creating a new theme hook, and then referencing that theme hook from the
$form array that defines the form. Doing so allows theme developers to customize the layout of the elements in the form using HTML and CSS.
This is useful when you want to change the layout of the entire form. For example, putting the elements into 2 columns. If you want to change individual elements in the form, you can often do so by overriding element specific Twig template files.
In this tutorial, we'll:
- Learn how to create a new theme hook that can be used to theme an element in a render array.
- Associate the
$formwe want to theme with the new theme hook we created.
- Create a Twig template file for the theme hook that will allow us to lay out the form elements using custom HTML.
By the end of this tutorial, you should be able to associate a Twig template file with any form in Drupal, so that you can customize its layout using HTML and CSS.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
