Module Development

Define a New Render Element Type for Drupal 8, 9, and 10

Modules can provide new render element types -- a powerful way to encapsulate complex logic into a reusable component. This can help to cut down on code repetition, and allow other module developers to build on your work. In this tutorial we'll:

  • Define a recipe for creating a new render element type
  • Look at the code for the marquee element type from the render_example module in the Examples for Developers project.

By the end of this tutorial you should be able to implement a new render element type in your own module and make use of it when defining content as part of a render array.
