Listbox Renderer

Here we describe how to implement a custom renderer for a listbox (ListitemRenderer). For the concept about component, model and renderer, please refer to the Model-driven Display section.

When a listbox (Listbox) is assigned with a model, a default renderer is assigned too. The default renderer will assume the listbox is a single column, and it converted the element into a string. If you want to display multiple columns or retrieve a particular field of the element, you have to implement ListitemRenderer to handle the rendering.
