title: How to style NamePicker using themes?
body: <p>How can I style NamePicker from extensions library using themes? I need to style it using Twitter Bootstrap, it means I need to assign 'btn' like class to all its buttons (add, ok, cancel etc.) and so on. I am able to assign class to common button on xpages using themes, but it doesnt influence buttons on NamePicker dialogue? Do they use some different theme id? How can I obtain it?</p>
  
  <p>I have looked into Boostrap4Xpages project source but cant figure out the proper technique. Something can be adjusted by themes and assigning proper class attriutes, sometimes the custom renderers has to be involved. But I cant find a way how it is for NamePicker. </p>
