                <p><span class="initial-space"></span><strong><span style="color:#c60d0d">IntegralUI</span> ListView</strong> is a native Angular component that displays list of items either in horizontal or vertical layout. Items can be reordered using advanced drag drop operations. You can load data on demand during run-time from local or remote data sources, and add custom HTML content in each item.</p>
                <p><span class="initial-space"></span>Above demonstration shows two different views:</p>
                    <ul class="feature-points">
                        <li>Horizontal layout where items are arranged from top to bottom with horizontal scrolling</li>
                        <li>Vertical layout where items are arranged from left to right with vertical scrolling</li>
                    </ul>           
                <p><span class="initial-space"></span>In addition, item content is arranged differently: horizontal layout shows item content in single line, while vertical layout shows item content in a box. Rating is displayed using the <a routerLink="/rating">IntegralUI Rating</a> component.</p>
                <p><span class="initial-space"></span>You can reorder items by click and drag over specific item. A dragging window will appear, stating the target item and position at which item can be dropped. During drag drop operations, you can also create a copy of an item by holding the SHIFT key. The dragging window will change its icon, showing a + sign next to position marker.</p>
