I am not sure how this has happened. but wherever I render the block of my main menu, it displays it's links horizontally rather vertically. Essentially I want to create a main menu that displays its links vertically.
Anybody have a lead on how this can be done ? I am tempted to go into the CSS and alter the theme myself but given that Drupal probably has a switch that allows me to alter the way a main-menu is listed, I want to caution myself.
