There are much better plugins out there now that do this. I recommend MMenu http://mmenu.frebsite.nl/
Creates drawer-style navigation on your mobile site, as seen on iOS.
$("body").mobile_menu({ menu: 'main-nav' });
menu: Target the menu you would like to convert to mobile. This option supports multiple menus by using an array rather than string.
page_id: Sets the ID of the div that will wrap your sites content. Defaults to 'build-menu-page'
menu_width: Width of the mobile menu
menu_id: Menu ID. Defaults to 'mobile-nav'
button_content: The html content of your button. Defaults to a text string of 'MENU'
prepend_button_to: By default the button content is prepended to the page wrapper ID. This allows you to prepend the menu button within some other container.
