[flexcoders] Would like to create a dynamic form

[timgerr]

Hello all,
I was wondering how to create a dynamic form using Action Script in
Flex.  Here is the Flex code:
<mx:Form>
        <mx:FormItem label="Test">
                <mx:TextInput id="New"/>
        </mx:FormItem>
</mx:Form>

I know how to declare the form:
var fm:Form = new Form();
but I am not sure how to add all the other stuff to it.  

Thanks for the help or read,
