Title: Suggested correction for issue #542

If the data-show="hover" option is used, clicking on the dropdown won't do anything, and preserves the formatting of the dropdown from the jQuery fadeout(), slideup() and hide() methods (which add a display: none, and make the hover option stop working).

data-show="hover" will override the data-effect options, and instantaneously display the menu when the mouse hovers over it.
