jquery Sortable - cant serialize data

[itxtme]

I have a sortable list that I want to save the items group. To be clear

List A
item 1
item 3

List B
item 2

I move item 2 into list B, then I need to save the fact that item 2 is in list B.

I have a form where I want, once the submit button is pressed, the lists orders to be saved as data and placed within the form for submission (hidden input) as a value.

I have tried to use the "toArray( options )" for the sortable UI, however I am using it in conjunction with a plugin to make it multi-selectible. I cannot for the life of me get the array into the from.

I have the basic setup in a jsfiddle

Any help much appreciated for this Jquery Noob

Took the dog for a walk when I had my sudden epiphany, put the inputs within the <li> items.

<li><input name="Item12" type="hidden" value="12" />Item 12</li>

I then use the form normally as I would any other content.

Working perfectly
