/**
* Breadcrumbs represents a Bootstrap 5 version of [[\yii\widgets\Breadcrumbs]]. It displays
* a list of links indicating the position of the current page in the whole site hierarchy.
*
* To use Breadcrumbs, you need to configure its [[links]] property, which specifies the links to be displayed. For example,
* This widget represents a Bootstrap 5 component "Breadcrumb". It displays a list of links indicating the
* position of the current page in the whole site hierarchy.
*
* ```php
* echo Breadcrumbs::widget([
* 'links' => isset($this->params['breadcrumbs']) ? $this->params['breadcrumbs'] : [],
* 'options' => [],
* 'links' => [
* [
* 'label' => 'the item label', // required
* 'url' => 'the item URL', // optional, will be processed by `Url::to()`
* 'template' => 'own template of the item', // optional
* ],
* ['label' => 'the label of the active item']
* ],
* 'options' => [...],
* ]);
* ```
* or
* ```php
* echo Breadcrumbs::widget([
* 'links' => [
* 'the item URL' => 'the item label',
* 0 => 'the label of the active item',
* ],
* 'options' => [...],
* ]);
* ```
