 * The tabs structure consists of an unordered list of tabs that have hashes corresponding to tab ids.
 * Then when you click on each tab, only the container with the corresponding tab id will become visible.
 *
 * You can use Tabs like this:
 *
 * ```php
 * echo Tabs::widget([
 *     'items' => [
 *         [
 *             'label' => 'Home',
 *             'content' => 'Home content...',
 *             'active' => true
 *         ],
 *         [
 *             'label' => 'Profile',
 *             'content' => 'Profile content...'
 *         ],
 *         [
 *             'label' => 'Messages',
 *             'content' => 'Messages content...',
 *             'disabled' => true
