NestedSortable Widget 介绍

The nestedSortable Widget (from Now on just widget) is a component that allows
you to create a multi-columned table of entries that can be sorted and nested
very easily by your user, using drag and drop, with full support for
pagination.

It is built on top of the plain
NestedSortable plugin and
will, basically, do almost all the work you would have to do if you were to
use the regular nestedSortable, as long as you provide it with a data source
that will pass in your list of nested elements in JSON format. Given that
list, it will build the HTML for the whole component, construct the
NestedSortable and show
visual clues as to when things are being loaded or saved.

The list items can have multiple columns, since the widget will draw your list
in a way that looks like a table. The widget also has support for pagination
of the list, both on the client (you don’t have to show the whole list at
once) and the server (you don’t have to download the whole list at once). This
can be a necessity when you are sorting a list with a large number of items.
The widget code, perhaps surprisingly, is almost 3 times larger than the
NestedSortable plugin’s
code. The good news is that all is already written for you and with it in your
hands you will be able to create a list that can be sorted and nested by your
user in no time.

You should check the
demo, to really
get a grasp of its main functionalities. Note that the data source used in the
demo is a little stupid: it won’t save the order of the elements, it will just
pretend it did.

This widget, along with nestedSortable, was designed as part of a Google
Summer of Code project for wordpress, in 2007, in order to provide a easy way
for users to sort their pages. You can see it in action for wordpress in my
blog.
