wp_dropdown_pages select current page

Hi guys,

I’m running into a bit of trouble using the wp_dropdown_pages function. I’m creating a dropdown list to link to certain pages using the following lines:

<form name="form1" action="" method="get">
			<?php $select = wp_dropdown_pages('show_option_selected=&depth=100&sort_column=menu_order&echo=0');
			$select = preg_replace("#<select([^>]*)>#", "<select$1 onchange='return this.form.submit()'>", $select);
			echo $select;
			?>
			<noscript><input type="submit" name="submit" value="" /></noscript>
			<input type="hidden" name="lang" value="<?php echo qtrans_getLanguage(); ?>">
		</form>

At the moment this code allows me to navigate to the page I select. What I’d like now is that it selects the current page in it’s value. I know there must be an option here to make WP do that.

Thanks in advance!
