Method Detail

renderOptions

void renderOptions(IMarkupWriter writer,
                   IRequestCycle cycle,
                   IPropertySelectionModel model,
                   Object selected)

Called after the initial <select> tag has been rendered. It is expected that implementations will then do whatever is necessary to render each option available in the model and defer writing the end </select> to the calling component.

Parameters:

writer - The markup writer to use.

cycle - The associated cycle.

model - Model containing values / labels / etc..

selected - The currently selected object value, if any. Will be null if no value is currently selected.
