Arrow navigation

[madmoizo]

I'm not really concerned about arrow navigation but if you want to improve it, there are uncommons behaviours.

First :

• Select an option
• Press enter to re-open the dropdown menu
• Press arrow up/down until to reach the first/last option of the list
• The next arrow up/down will lead to the selected option instead of the last/first option of the list

Second : If you have a scrollbar in dropdown menu (use of data-size) and you press arrow key, the scrollbar don't follow the "focused" option
