There is a setting in the CSS that prevents the wrapping:
#ddmenu a
{
....
white-space:nowrap;
}
You can remove the nowrap setting and replace it with: max-width:180px;
If you are talking about the sub-menu items, you can leave above setting un-touched and just update the sub-menu links as:
#ddmenuMst div.drop a
{
....
white-space:normal;
max-width:180px;
}
