No doubt, you should consider simplifying this menu by classifying and regrouping menu items. In this form your menu is simply not usable, so instead of trying to display this, try to simplify it first, and the solution will come naturally.
In other words - "divide to conquer".
There is always a way to classify 17 elements in not more then 5 or 6 on the top level.
A simple example - "Member ID" and "Member Search" could probably belong to a same "Member" Menu. You should also consider submenu items and not only these 17. They can probably be somehow reorganized and restructured so you have not more then 5-6 items in each group.
