Dropbutton

Provides a render element for a set of links rendered as a drop-down button.

By default, this element sets #theme so that the 'links' theme hook is used for rendering, with suffixes so that themes can override this specifically without overriding all links theming. If the #subtype property is provided in your render array with value 'foo', #theme is set to links__dropbutton__foo; if not, it's links__dropbutton; both of these can be overridden by setting the #theme property in your render array. See template_preprocess_links() for documentation on the other properties used in theming; for instance, use element property #links to provide $variables['links'] for theming.

Properties:

• #links: An array of links to actions. See template_preprocess_links() for documentation the properties of links in this array.

Usage Example:

$form['actions']['extra_actions'] = array(
  '#type' => 'dropbutton',
  '#links' => array(
    'simple_form' => array(
      'title' => $this->t('Simple Form'),
      'url' => Url::fromRoute('fapi_example.simple_form'),
    ),
    'demo' => array(
      'title' => $this->t('Build Demo'),
      'url' => Url::fromRoute('fapi_example.build_demo'),
    ),
  ),
);
