Creating a “Tags” page with search option, instead of using a widget

Create a file in your theme called for example : myTagsPage.php

in it paste the following code

<?php
/*
Template Name: myTagsPage
*/
<h2>Actors</h2>
<?php the_tags('<ul><li>','</li><li>','</li></ul>'); ?>
?>

then in administration, create a new blank page, on the right side, you should be able to choose which template you want – pick myTagsPage

you can choose many functions, play with the parameters – i wrote a sample one

I saw a plugin for this once, but i guess this is more flexible and you can customize it more 🙂
