The main menu should open when hovered over. It does it for everything but the Shop Tab because it is built as a static block. How can auto-open be enabled even for the Shop sub-menu?
Also, when no longer hovering over the menu, it should auto-close but the Static Block remains open.
Lastly, https://safedesires.com/staticblocks/static-shop/ is formatted correctly by itself, but the 3-column width forces the right-side images to extend past the boxes.
