How to configure the dropdown list?

Welcome!

Wrote a small menu with a dropdown list , for clarity, are interested in 3 questions:
1. How to make a dropdown list appear OVER and not UNDER the parent?
2. How to make a drop down list starts from the right edge of the parent and continued to the left side?
3. How to do to with the lack of space on the right, drop down the list was the free space on the left?
