<rich:calendar popup="true" id="test" style="padding:10px;"/>
Works for me in IE and FF. also you may define it in your styleClass. Unfortunatelly we've forgot to add default rich-* class to div. Also be carefull about autopositioning. If you leave it on the result may be not everything right.
Thank you ilya for your time
padding gives a white border on IE6 in our application and does not work in FF.
Direction and jointPoint attributes give some control over the positioning, and this is sufficent for our current needs. Maybe you could sign x,y offset as feature request.
