    menuId      - id string of menu.
    mouseMargin - integer margin around menu;
                  when mouse is outside this margin the menu is hid.
    slideTime   - integer time for menu slide (in milliseconds).
    openEvent   - string name of event on which to open menu ('click', 'mouseover', etc).
