Hmm....
Assuming that all spells are tagged with "Spell" plus some unique class
tag, you could just use "Spell" as the value for the "all" option, and just
filter by the selected_class value, like this:
<div class='input'>
<label>Filter by Class</label>
<$select field='selected_class' default='All'>
<option value='Spell'>All</option>
<$list filter='[tag[Class]]'>
<option value={{!!title}}>{{!!title}}</option>
</$list>
</$select>
</div>
<ul>
<$list filter="[tag{!!selected_class}]">
<li>{{!!title}}</li>
</$list>
</ul>
That should get you what you want. Let me know how it goes...
