We have recently made a necessary change to the Moriarty skin that will effect 100% of our users using this skin. The top navigation which was originally on the right side of the screen was not working well with multi-teared drop downs. The drop down menus are too close to the right side of the screen and would pass beyond the screen obscuring menu items.
Here is an example of the issue.
Here is an example of the change, showing how the menu is now visible.
Prefer navigation on right?
In some instances the navigation may need to be on the right. If the branding background set in skins has an image that fits the location of the navigation. Of if you prefer it on the right and your site does not have any nested drop downs then you can use the following css in the head of your site to move the navigation back to the right.
