Link to header example:http://callmenick.com/_development/resize-header-on-scroll/
We have not had other requests for other mobile menus, and that is a very involved project to add more. We do not currently have plans of adding another kind, but we will certainly consider it.
You don't need to add it for me as third option. I think replace the dropdown. The buttons/links are very small on mobile.
The language controller is always very hard to fit in, with responsive sites it difficult to get too much in the header.
This is a request/comment that I get all the time..
It is not about design, this is about functionality for multi language websites. Functionality should be above design in my opinion for good working websites. The moment a vistors has to start searching is also the moment they are at the point of leaving the site. Just my thoughts.
