The horizontal menu bar below is created using both jsDOMenu and jsDOMenuBar. jsDOMenu is used to create the menus, while jsDOMenuBar is used to create the menu bar. In addition, the menu bar below is draggable. You can position your cursor to the dragging region (the leftmost edge) of the menu bar to drag it.

Source code for creating menu bars and menus in this page:

function createjsDOMenu() {
  absoluteMenu1 = new jsDOMenu(120, "absolute");
  with (absoluteMenu1) {
    addMenuItem(new menuItem("Item 1", "", "blank.htm"));
    addMenuItem(new menuItem("Item 2", "item2", "blank.htm"));
    addMenuItem(new menuItem("Item 3", "", "blank.htm"));
    addMenuItem(new menuItem("-"));
    addMenuItem(new menuItem("Item 4", "", "blank.htm"));
    addMenuItem(new menuItem("Item 5", "", "blank.htm"));
  }
  
  absoluteMenu1_1 = new jsDOMenu(130, "absolute");
  with (absoluteMenu1_1) {
    addMenuItem(new menuItem("Item 1", "", "blank.htm"));
    addMenuItem(new menuItem("-"));
    addMenuItem(new menuItem("Item 2", "", "blank.htm"));
    addMenuItem(new menuItem("Item 3", "", "blank.htm"));
    addMenuItem(new menuItem("-"));
    addMenuItem(new menuItem("Item 4", "", "blank.htm"));
  }
  
  absoluteMenu2 = new jsDOMenu(120, "absolute");
  with (absoluteMenu2) {
    addMenuItem(new menuItem("Item 1", "", "blank.htm"));
    addMenuItem(new menuItem("Item 2", "", "blank.htm"));
    addMenuItem(new menuItem("Item 3", "", "blank.htm"));
    addMenuItem(new menuItem("-"));
    addMenuItem(new menuItem("Item 4", "item4", "blank.htm"));
  }
  
  absoluteMenu2_1 = new jsDOMenu(150, "absolute");

  }

  with (absoluteMenu3) {
    addMenuItem(new menuItem("Item 1", "item1", "blank.htm"));
    addMenuItem(new menuItem("Item 2", "", "blank.htm"));
    addMenuItem(new menuItem("-"));

    addMenuItem(new menuItem("Item 5", "", "blank.htm"));
  }
  
  absoluteMenu1.items.item2.setSubMenu(absoluteMenu1_1);
  absoluteMenu2.items.item4.setSubMenu(absoluteMenu2_1);
  absoluteMenu3.items.item1.setSubMenu(absoluteMenu3_1);
  
  absoluteMenuBar = new jsDOMenuBar("absolute", "", true);
  with (absoluteMenuBar) {
    addMenuBarItem(new menuBarItem("Item 1", absoluteMenu1));
    addMenuBarItem(new menuBarItem("Item 2", absoluteMenu2));
    addMenuBarItem(new menuBarItem("Item 3", absoluteMenu3));
    moveTo(10, 130);
