                <p><span class="initial-space"></span><strong><span style="color:#c60d0d">IntegralUI</span> ContextMenu</strong> is a native Angular component that allows you to attach a custom context menu to any HTML element or Angular component. Whenever element is right-clicked, a context menu will popup showing data provided on your side.</p>
                <p><span class="initial-space"></span>In this example, whenever the block is right-clicked, a context menu will appear with options from where you can change the font style of the block content. These options are divided in two groups using a separator. Options in the first group have a checkbox, while in the second have a radio button. Depending on which option is active, the font style of the block content changes accordingly.</p>
