How to display tags inline?
You can use CSS to style the tags.

If your html output is this:

&lt;ul class="tags"&gt;
    &lt;li&gt;Tag 1&lt;/l1&gt;
    &lt;li&gt;Tag 2&lt;/l1&gt;
    &lt;li&gt;Tag 3&lt;/l1&gt;
    &lt;li&gt;Tag 4&lt;/l1&gt;
&lt;/ul&gt;


Then use the following CSS to align tags horizontally. 

.tags li { display:block; float:left; }
