Dynamically enable or disable a component

Hi,

I need to know that how we can dynamically disable and enable a component (say dropdown) by selecting a paricular value of a radio button in JSF.

Please help me as I'm new to this technology..

Regards,

Debashis

define disabled="#{viewBean.isTheComponentDisabled}" at component. And manage via ajax.

Thanks for your prompt reply. Partial code has been given below. What I need to do is by selecting any of the radio button I need to disable/enable a particular set of dropdowns. Could you please suggest how I can do with ajax?

<h:selectOneRadio id="startServerRadio"
                      value="#{fileSourceConfigBean.startServerMode}" >
                           <f:selectItem itemValue="immediate" itemLabel="Start the transfer process immediately"/>
                         <f:selectItem itemValue="schedule" itemLabel="Schedule transfer"/>
</h:selectOneRadio>
