html - how to get jquery selectable to select elements from other divs -

-

i working on requires me have li's in different parents. using jquery selectable function of selecting li's , ability drag mouse select multiple li's.

this working great apart fact need someway of including of li's under both parents when selected rather acting 2 seperate containers.

so in example, when drag on numbers select in first block not move onto second block starting @ number 13.

i need include of numbers somehow without having move of li's same parent container.

script:

+$(function() {     $( "#selectable, #test" ).selectable();   });

try adding listener parent group, in case body.

+$(function() {     $( "body" ).selectable(); });
