Title: Allow to reuse dropdown-content element. 

If a target opened the dropdown, clicking another target will directly open the same dropdown element instead of just closing the previous one.
Although an edge case, it is very useful for dropdowns that act as a host to some ajax content.
See https://github.com/zurb/foundation/issues/4811 for more details.

Remove unnecessary call to this.close.call
