wp_dropdown_pages cannot be styled and some parameters do not work

I am trying to list child pages of a cetain page. The ‘child=’ parameter works well, but other functions, such as ‘selected=’, do not work, and especially styling this function is a sheer nightmare.

<div id="pages">
 <h3><?php _e('Search'); ?></h3>
   <form action="<?php bloginfo('url'); ?>" method="get">
   <?php wp_dropdown_pages('child_of=199'); ?>
   <input type="submit" name="submit" id="submit" value="VIEW" />
   </form>
</div>

One can set the width of the <div id=pages>, but the form itaself will overflow the div width. One can reduce the width of the <option> but the dropdown window will remain at set width which remains outside the boundaries of the <div> surrounding it.

There is no styling options or parameters on the wp_dropdown_pages Functions Refence page : Function Reference/wp dropdown pages

Is there a set pixel width in the WP source code for the wp_dropdown_pages function?

Does anyone else have problems with this function?
