You won't be able to do this with a ListBox, because it just creates an HTML < select> element.

You can use a MenuBar that has one menu with MenuItems in it to simulate a dropdown with complex widgets inside it. You will also be able to style the dropdown rather than rely on browser-styled form elements.

Take a look at the Combobox or Suggestion box in Advanced GWT Components.

Another widget is the DropDownListBox in the GWT incubator. I have not used it, but the stated intent is to provide a rich, stylable ListBox. You can pass raw HTML to the addItem() method.

DropDownListBox

it is possible to use Tree inside ScrollPanel, without using nested items Tree allows TreeItem to be a Widget
