Over the past couple years I’ve really enjoyed monitoring trends in the blogosphere and one of the trends that has come up recently is blogger’s cleaning up their sidebars by adding drop-down boxes.

If you’d like to build drop-down boxes for your categories and archives on your WordPress blog, here is the code you need:

Archives Drop-down Code

<select name="archive-dropdown" onChange='document.location.href=this.options[this.selectedIndex].value;'>
<option value=""><?php echo attribute_escape(__('Select Month')); ?></option>
<?php wp_get_archives('type=monthly&format=option&show_post_count=1'); ?> </select>

Categories Drop-down Code

<form action="<?php bloginfo('url'); ?>/" method="get">
<?php
$select = wp_dropdown_categories('show_option_none=Select category&show_count=1&orderby=name&echo=0');
$select = preg_replace("#<select([^>]*)>#", "<select$1 onchange='return this.form.submit()'>", $select); echo $select; ?>
<noscript><input type="submit" value="View" /></noscript>
</form>

I think something like this can be a good idea if done with the right theme, but I have also seen it on a few sites where it didn’t look very good, so keep that in mind if you decide to move your categories and archives to a drop-down box!
