Почему в отладчике не отображаются: 'li itemprop', 'span itemprop', 'meta'?
а должно быть как-то так;

* with the following structure:
*
* ```php
* [
* 'label' => 'label of the link', // required
* 'url' => 'url of the link', // optional, will be processed by Url::to()
* 'template' => 'own template of the item', // optional, if not set $this->itemTemplate will be used
* ]
* ```
*
* If a link is active, you only need to specify its "label", and instead of writing `['label' => $label]`,
* you may simply use `$label`.
*
* Since version 2.0.1, any additional array elements for each link will be treated as the HTML attributes
* for the hyperlink tag. For example, the following link specification will generate a hyperlink
* with CSS class `external`:
*
* ```php
* [
* 'label' => 'demo',
* 'url' => 'http://example.com',
* 'class' => 'external',
* ]
* ```
*
* Since version 2.0.3 each individual link can override global [[encodeLabels]] param like the following:
*
* ```php
* [
* 'label' => '<strong>Hello!</strong>',
* 'encode' => false,
* ]
* ```
