Change Block Format Dropdown in the Visual Editor

Have clients that insist on using <h1> tags throughout their posts? Can’t remember the last time you used the <address> tag? This can help you clean up that block format dropdown menu.

add_filter('tiny_mce_before_init', 'change_mce_dropdown' );
function change_mce_dropdown( $initArray ) {
	$initArray['theme_advanced_blockformats'] = 'p,h3,h4,h5,h6,pre';
	return $initArray;
}
