<h1>Sortables</h1>
<h2>Introduction</h2>
<p>
Back in the 90s you sorted items in a list with arrows up/down or maybe even
with input-fields where you specified the item"s position. But now you have the
Sortables-Plugin, which comes in handy when you are using one or more lists
and need the user to sort them.
</p>
<div id="sortablesDemo">

</div>
<hr />
<h2>Advanced Example</h2>
<p>
The advanced example shows, that it is even possible to drag&drop list-elements
into another list.

<h1>Dynamic Sortables</h1>
<h2>Introduction</h2>
<p>
This To Do list is a good example of using Sortables in lists which have items dynamically added. Notice that on line 47 of the JavaScript file, we make a call to sort.addItems(). It is critical that we call this method on our Sortables object every time we add a new item to the list.
</p>
<h2>My To Do List</h2>
<form id="addTask">
<input type="text" id="newTask" />
<input type="submit" value="Add Task" />
</form>
<div id="listArea">
<ol id="todo"></ol>
</div>
<div id="data"/>
</body>
