I have seen a number of questions about this, but i am still unable to fix.
I am using the responsive theme, and have created a child theme for it.
I have placed a logo next to my menu in the header, exactly as i want it and it works perfect.
The only problem is the responsive behavior. When viewed on a small screen the menu collapses onto two rows until the alternative menu takes over, and when that menu takes over, it does not open completely (i think because i inserted another full width image in the header). so there are actually two problems.
