Display Category in a Dropdown Menu

Some blogs have a lot of categories which they can’t display in their sidebar. Or some bloggers do not want to take up a lot of space displaying categories. This option allows them to have a select menu, dropdown menu, for categories. See WordPress Codex for details.

$select = wp_dropdown_categories('show_option_none=Select Category&show_count=1&orderby=name&echo=0&selected=6');
$select = preg_replace("#]*)>#", "", $select);
echo $select;
?>





Exclude Certain Categories from Being Displayed in a Loop

Your blog page shows recent posts from all categories. If you want to have a separate page for some reason, or do not want to display certain categories, you can use the following code, and it will exclude a certain category from being displayed in a Loop. Just change the category IDs.
