To change all dropdowns, top and bottom, width 500px, top options box (1):
ul.top-navigation li li a:visited,
.top-navigation ul ul a,
ul.bottom-navigation li li a:link,
ul.bottom-navigation li li a:visited,
.bottom-navigation ul ul a {
width:500px;
}
</style>
To change sub menu and subsequent sub-menus View Source, find id of sub-menu (eg by creating menu with word ‘elephant’ and then searching for ‘elephant’):
<style type="text/css">
ul.top-navigation li li#menu-item-243 a:link,
ul.top-navigation li li a:visited,
.top-navigation ul ul a {
width:500px;
}
</style>
To change one specific sub-menu item only and NOT subsequent ones (hopefully):
<style type="text/css">
ul.top-navigation li#menu-item-243 li a:link,
ul.top-navigation li li a:visited,
.top-navigation ul ul a {
width:500px;
}
</style>
