i think this is the plugin

 

thanks QueenEve, but I believe that last plugin you post is a dropdown function for wordpress menu not for blogroll.
I try to find a specific blogroll dropdown list plugin..

 

Ok I did some search and found this plugin : http://www.dagondesign.com/articles/drop-down-post-list-plugin-for-wordpress/

but its a dropdown list for post,
anyone know to to mod it to view a blogroll on particular category?
thanks.
