I have an archive dropdown working as follows:
<select onchange="if (this.selectedIndex != 0) { window.location = this[this.selectedIndex].value; }">
<option>Choose Month...</option>
<?php get_archives('monthly','','option'); ?>
</select>
I think a category dropdown that works in a similar fashion would be great e.g. get_categories('format', 'name', 'before', 'after'); ?>
<select onchange="if (this.selectedIndex != 0) { window.location = this[this.selectedIndex].value; }">
<option>Choose Category...</option>
<?php get_categories('option', 'name'); ?>
</select>
Of course this is not possible at the moment using the dropdown_cats function as it creates the <select>, therefore preventing me from adding the onchange attribute. It also sets the value attribute of each option to it's index rather than the category URL which is required for changing the window.location.
Has this type of functionality been considered before?
