How to get one radio button in one line in struts2

[DMaharana]

When using the s:radio-botton I get all the radio buttons in one line.

<s:radio label="Foo" name="foo" list="foo"/>

Is there a possibility to get each redio button in one line?

I tried:

<s:radio label="Foo" name="foo" list="foo">
   < b r />
 </s:radio>

It won't work.
