class UIkitAccordion in UIkit Components 8.3

Provides a render element for the Accordion component.

Properties:

  • #items: An array of items to be displayed in the accordion. Each item must contain the title and content properties.
  • #component_options: An array containing the component options to apply to the accordion. These must be in the form of "option: value" in order to work correctly.

Usage example:

$form['accordion'] = [
  '#type' => 'uikit_accordion',
  '#items' => [
    [
      'title' => $this
        ->t('Item 1'),
      'content' => Markup::create($item_one),
    ],
    [
      'title' => $this
        ->t('Item 2'),
      'content' => Markup::create($item_two),
    ],
    [
      'title' => $this
        ->t('Item 3'),
      'content' => Markup::create($item_three),
    ],
  ],
  '#component_options' => [
    'multiple: false',
    'duration: 500',
  ],
];
