                <p><span class="initial-space"></span><strong><span style="color:#c60d0d">IntegralUI</span> Breadcrumb</strong> is a native Angular component used for navigation, where each item can have a link that is automatically separated. The component is fully customizable via CSS.</p>
                <p><span class="initial-space"></span>In this example, there is a small tree hierarachy where only currently selected path is shown. Initialy item named 'Downloads' is selected, and the Breadcrumb shows the whole path that leads to this item. By clicking on the separator (arrow button), a dropdown list will popup where you can select a different item.</p>
                <p><span class="initial-space"></span>By default, links are not created, but you can customize the item template and add your own links either using the hyperlink tag or set navigation through code by handling  the selectionChanged event.</p>
                <p><span class="initial-space"></span>The following properties and events are supported:</p>
                <ul class="feature-points">
