Drupal 8 Module Development - Second Edition

Rendering a layout

OK, but registering a layout doesn't help us with much. Unless, of course, we use Layout Builder or some contributed module that uses layouts for various things.

The simplest way of rendering something with this layout could look like this:

$layoutPluginManager = \Drupal::service('plugin.manager.core.layout'); 
$layout = $layoutPluginManager->createInstance('two_column'); 
 
$regions = [ 
  'left' => [ 
    '#markup' => 'my left content', 
  ], 
  'right' => [ 
    '#markup' => 'my right content', 
  ], 
]; 
 
return $layout->build($regions);
