+          <h3>Example</h3>
+          <p>The <code>SplitButton</code> component emits three events, "click" when the button itself is clicked, "show" and "hide" for when the contents display is toggled. This component is abstract, it is not bound to a <code>Menu</code> or <code>ColorPicker</code> etc, one should inherit from this component to display content.</p>
