I have two problem,
This nestedSortable is not working in this code, where's the problem ?
I want to block a user to drag an sub-element to the top level (base), i know the library does not allow it, is there a tweak ?
Here is all my code :
<html>
<head>
<style>
html {
background-color: #eee;
}
body {
color: #333;
background-color: #fff;
font-size: 13px;
font-family: "Helvetica Neue", Corbel, "Nimbus Sans L", Helvetica, Arial, sans-serif;
padding: 2em 4em;
width: 860px;
margin: 0 auto;
}
pre, code {
font-size: 12px;
}
pre {
width: 100%;
overflow: auto;
}
small {
font-size: 90%;
}
small code {
font-size: 11px;
}
.placeholder {
background-color: #cfcfcf;
}
.ui-nestedSortable-error {
background:#fbe3e4;
color:#8a1f11;
}
ul{
margin: 0;
padding: 0;
padding-left: 30px;
}
ul.sortable, ul.sortable ul{
margin: 0 0 0 25px;
padding: 0;
list-style-type: none;
}
ul.sortable {
margin: 4em 0;
}
.sortable li {
margin: 7px 0 0 0;
padding: 0;
}
.sortable li div {
border: 1px solid black;
padding: 3px;
margin: 0;
cursor: move;
}
h1 {
font-size: 2em;
margin-bottom: 0;
}
h2 {
font-size: 1.2em;
font-weight: normal;
font-style: italic;
margin-top: .2em;
margin-bottom: 1.5em;
}
h3 {
font-size: 1em;
margin: 1em 0 .3em;;
}
p, ol, ul, pre, form {
margin-top: 0;
margin-bottom: 1em;
}
dl {
margin: 0;
}
dd {
margin: 0;
padding: 0 0 0 1.5em;
}
code {
background: #e5e5e5;
}
input {
vertical-align: text-bottom;
}
.notice {
color: #c33;
}

</html>
Thanks ! :)
EDIT : here is a working exemple http://mjsarfatti.com/sandbox/nestedSortable/ If I can only get this work, maybe I could look more for my second point
EDIT 2 : I'Ve changed the library as one of the answer told me, but firefox is hanging and there's un unresponsive script
Here is the fiddle : http://jsfiddle.net/dAwEe/2/
EDIT 3 : Someone have an idea ?
EDIT 4 : http://jsfiddle.net/dAwEe/3/ I've fixed my problem one : The nested sortable js was not well include :S
Now someone have an idea for the problem two ?
I modified the code a little with $.extend() and I think I came pretty close --> http://jsfiddle.net/Galled/dAwEe/85/
From the plugin website:
Requires:
jQuery 1.4+
jQuery UI Sortable 1.8+
Probably will not solve your problem, but not all browsers support empty tag notation for script tags. You need to close them with a closing script tag.
<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js' type='text/javascript'/>
Needs to be
<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.4/jquery.min.js' type='text/javascript'></script>
Problem two:
isAllowed can be used to enable or block a position. To block the root position, you can use codes like this:
isAllowed: function (item, parent) {
if (parent == null) { //Parent == null means the root.
return false;
}
}
see more information here: NestedSortable: isAllowed() does not work when connectWith() is used
