<p><b>Updated 4/26
</b> - moved to new DnD sorting code. In-place edit still written as ad hoc scripts
in the HTML source.
</p>
</div>
<p>Edit in place (also called in-place editing) follows the
axiom Alan Cooper calls "allow input wherever you have output". The
combobox – a form element unfortunately absent from HTML –
demonstrates this. In the same place where the current selection is
displayed, the user can enter a value directly.
</p>
<h2>Editable Content
</h2>

<textarea id="paragraphEdit" class="inplace" tabindex="1">
</textarea>
<div class="sidebar">
<p>Firefox, you cannot cancel the TAB key from moving focus around. If you press TAB while editing the first editable paragraph on the left, then
you end up focused here:
<input id="focusSink" type="text" readonly="" size="13" onfocus="this.value='focus is mine'" onblur="this.value=''" tabindex="2"/>
</p>
</div>
<div id="markupView">
<p>Editable #2: This can work on arbitrary markup. This may or may not be such a good idea.
</p>
<p>We can do paragraphs,
<b>styling
</b>, <a href="./index.html">links
</a>,
or any HTML, really.

<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

<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="sorting.html">DnD Sortable Lists
</a>.
</p>
</div>
<p>Combining in place editing with
<a href="sorting.html">Drag & Drop Sortable Lists
</a> results in
nice direct manipulation for managing a list of labels.

<h2>Known Bugs
</h2>
<ul>
<li><p>Safari 1.2: Extra whitespace is introduced by the "Edit Markup" example (resolved in 1.3).
</p></li>
<li><p>Positioning text inputs over labels doesn't work as well in
Safari 1.2 as in Firefox. Sizing inputs via CSS doesn't work in
Safari 1.2 (resolved in 1.3)
</p></li>
<li><p>Safari 1.2 has issues making the dragged item transparent.
Following siblings become transparent as well. (resolved in 1.3)
</p></li>
<li><p>Firefox 1.0: you can be editing a label and
start a drag without the label reverting back to display. This is more
easily demonstrated on the slideshow example. A mousedown anywhere
outside the text box should cause it to lose focus. Fixable with
JavaScript
</p></li>
</ul>
<h2>TODO
</h2>
<ul>
<li>Try out using createElement instead of including "hidden" input
elements in the markup
</li>
