Add html component at combobox

Flow
1

Hello,
I was wondering if it is possible to add a button(show more…)as an option at my combobox.
I tried this but it didn’t work.

Button button = new Button(“more”);

comboBox.getElement().appendChild(button.getElement());

There seems not to be direct access to it. The addToPrefix(…) method is protected (which I assume adds component to prefix slot of the text field used in ComboBox). So you can try extending ComboBox and using that one and check if it works (I did not have time to test).

public class MyCombo<T> extends ComboBox<T> {
	public MyCombo() {
		...
		this.addToPrefix(components);
	}
}
