<p>Without applying some kind of limitation, any markup whatsoever can be
entered. In practice you would normally want to limit the type of markup
allowed perhaps via a <a href="http://tinymce.moxiecode.com/">wysiwyg editor</a>
or a text formatter like <a href="http://daringfireball.net/projects/markdown/">Markdown</a>.

<h2>Sortable, Editable Lists</h2>
<div class="sidebar">
<p>Firefox and Safari register 'click' events after a drag causing the
field to become editable, which is undesirable. This is the same
problem with the sortable links and buttons example in
<a href="http://tool-man.org/examples/sorting.html">DnD Sortable Lists</a>.</p>
</div>
<p>Combining in place editing with
<a href="http://tool-man.org/examples/sorting.html">Drag & Drop Sortable Lists</a> results in
nice direct manipulation for managing a list of labels.</p>
