Sortable.create does not work with nested ul's unless you declare it a
tree. The problem is that I only want each child li to be sortable
within it's parent ul. Each time I created the sortable for the child,
the Sortable for the parent was destroyed because it was already in the
list and returned as the _findRootElement value.
I'm thinking that Sortable.options should only find the root element if
Sortable.create is dealing with a tree. If it's not, it should only
check for the actual element we are dealing with. Does what I said make
sense?
I got around the issue by overwriting how Sortable.options works before
I create my sortable and then overwriting it again with the original
code immediately after creating the sortable like so (an excerpt from
the class I created):
makeSortable: function() {
/**
* Make sortable options method work the way i want;
* I rewrite it to work like the original at the bottom of this
file.
*/
Object.extend(Sortable, {
options: function(element) {
element = $(element);
if(!element) return;
return Sortable.sortables[element.id];
}
});
/**
* Create my sortable
*/
Sortable.create(this.element.id, {
handle: this.options.handle,
onUpdate: function() {
new Ajax.Request(this.options.reorderUrl, {
method: 'post',
postBody:
Sortable.serialize(this.element.id, { name:
this.options.postVarName })
});
}.bind(this)
});
/**
* Make scriptaculous options work like the originally did
*/
Object.extend(Sortable, {
options: function(element) {
element = Sortable._findRootElement($(element));
if(!element) return;
return Sortable.sortables[element.id];
}
});
},
