javascript - Behaviors of JQuery sortable and draggable -

-

i have 2 draggable objects 'field' , 'container' , sortable object 'ui-main'. want drag 2 above objects 'ui-main', , allow add objects 'container', creating nested sortable form.

here demo: https://jsfiddle.net/tblaziken/a2qbnygb/1/

the javascript far:

$('.ui-select .ui-select-item').draggable({     revert : "invalid",     helper: 'clone',     connecttosortable : '.ui-sortable' });  $( ".ui-sortable" ).sortable({     connectwith: '.ui-sortable',     placeholder: 'ui-hovering' });

the problem can add or move new object ui-main , 2 existed ui-container objects, unable newly created ui-container. makes existed , newly created ones different , how fix it?

for me in jsfiddle works expected. however, use clone helper, not give full control on happens when clone. jquery's clone() function expects 2 parameters.

.clone( [withdataandevents ] [, deepwithdataandevents ] )

so have same events on every element either clone them yourself, setting both params true, or bind/unbind events again every newly added object.
