remain hidden. However, every tag is still accessible to screen readers &
text browsers.  The HTML looks something like this:

<div>
<a href="#tag-a">a</a>
...
</div>

<ul id="tag-a" class="tags">
  <li>alphanumeric</li>
  <li>animal</li>
</ul>

<ul id="tag-z" class="tags">
  <li>zebra</li>
</ul>

*Snags*
The Genshi template ckan/templates/layout_base.html asks for optional head
components in at the end of the head block. This means that any CSS imported
overrides the defaults. This means that downloading from
ajax.googleapis.com/.../jqueryui.css is fast, but leads to inconsistent
styling.

Feedback welcome. If people think this is a beneficial suggestion, I'll add
some polish and submit a patch.

Charles Coxhead (<a href=3D"http://twitter.com/charlescoxhead" target=3D"_b=

which can be found here: 
 
<a href=3D"http://www.quicksitereviews.com/ckan-net/" target=3D"_blank">htt=
p://www.quicksitereviews.com/ckan-net/</a> </blockquote><div> I have =
implemented one of the suggestions in this video. Of all the points in here=
, I think alphabetical pagination of tags would make the biggest difference=
 to users of CKAN. I&#39;ve crafted a fairly attractive solution with JQuer=
yUI&#39;s tabs. I thought I would discuss the solution before I worry about=
 finishing touches like getting JQuery&#39;s CSS to comply with CKAN&#39;s =
default styles.

The problem Currently, CKAN uses Pylon&#39;s pagination helpe=
r. Which is great at doing what it does, but it uses numerical values. When=
 people visit <a href=3D"http://www.ckan.net/tag/" target=3D"_blank">http:/=
/www.ckan.net/tag/</a>, they encounter pages 1 ... 16. But, if they&#39;re =
looking for a specific tag, it wouldn&#39;t help them too much. 
 My approach The tags controller: Select all tags from the db =
by recycling the SQLAlchemy Query object that is already there. From there,=
 create a dict with the 0th letter of each tag as its keys. This results in=
 something like: 
 tags =3D dict(</spa=
n> =A0 a=3D[&#39;alphanumeric&#39;, &#39;animal&#=
39;, ... ], 
=A0 z=3D[&#39;zebra&#39=
;] ) From there, the templat=
e renders every tag. Using CSS magic, most tags remain hidden. However, eve=
ry tag is still accessible to screen readers &amp; text browsers.=A0 The HT=
ML looks something like this: 
 &lt;div&gt; &lt=
;a href=3D&quot;#tag-a&quot;&gt;a&lt;/a&gt; 
... &lt;/div&gt; 
 &lt;ul id=3D&quot;tag-a&quot; class=3D&quot;tags=
&quot;&gt; =A0 &lt;li&gt;alphanumeric&lt;/=
li&gt; 
=A0 &lt;li&gt;animal&lt=
;/li&gt; &lt;/ul&gt; 
 &lt;ul id=3D&quot;tag-z&quot; class=3D&quot;tags=
&quot;&gt; 
=A0 &lt;li&gt;zebra&lt;/li&gt; 
&lt;/ul&gt; Snags The Genshi template ckan/template=
