Are you achieving this category drop-down with a plug-in at present? If so, you could modify it slightly. I am not aware of any existing plug-ins that do this, but what you want is probably something like the following.
In the header:
<script type="text/javascript">
function formHandler(form){
var URL = document.form.site.options[document.form.site.selectedIndex].value;
window.location.href = URL;
}
</script>
In the body:
<form name="form">
<select name="site" size=1 onChange="javascript:formHandler()">
<option value="Get_item_1_url()">Get_item_1_title()
<option value="Get_item_1_url()">Get_item_2_title()
</select>
</form>
where item_1 is the most recent one. I don’t know the WordPress API quite so well, but you can have a look at the WordPress Codex. Maybe somebody else in the forum can complete this. Hope it helps…
I’m sure he’s using the template tag Template_Tags/dropdown_cats. I wonder if a modified loop using query_posts would do it.
For the categoriese pull down menu I’m using this plugin.
For montly archives I’m using this code, which I got from the forums:
<form id="archiveform" action="">
<select name="archive_chrono" onchange="window.location =
(document.forms.archiveform.archive_chrono[document.forms.archiveform.archive_chrono.selectedIndex].value);">
<option value=''>Select Month</option>
<?php get_archives('monthly','','option'); ?>
</select>
</form>
