I have a simple question. I'm trying to make all my dropdowns in my sidebar the exact same width. I can easily set a fixed width for my non-widget HTML dropdowns, adding style="width:297px" to the <select> command. I'm trying to do this to the WP Categories Dropdown Widget, but I don't know PHP well enough to know where or how to do this. I've been looking through widgets.php, but haven't found any clues. Please help!
