In the attached example, if you drag Parent 2 in IE6/IE7, the nested list disappears. If you remove ""position: relative"" from the li style definition, the issue disappears, however you're limited with formatting as the alignment of the nested list is thrown out. A similar effect happens with float. {{{ Untitled Document }}} This is in both 1.7.2 and 1.8a1 A workaround (at least for the moment) is to:[[BR]] 1. remove ""position: relative""[[BR]] 2. add ""position: relative"" to the upper-most parent ul style[[BR]] 3. on the ""stop"" event of the sortable, use the jQuery position() to determine the top value, and then set this to be the absolute position of the child ul Visually, it will line up, but is an additional workaround.",bug,closed,major,2.0.0,ui.sortable,1.7.2,patcheswelcome,,,,
