/*----------------------------------
usage example:
on every call it changes the item to be displayed or not.

<input type="radio" name="rights" value="yes" onClick="hide_display(this,'rights_details');"> a
<input type="radio" name="rights" value="no"  onClick="hide_display(this,'rights_details');" checked> b
		
if block is used and the function is repeated on a tr it keeps on adding space.. so better to use ""
