For some reason, the height isn’t collapsing. It’s a floating group that floats relative to the top
What are you expecting it to do in this case? I’m not sure what is actually happening, or what your desired behavior is. Can you provide some more details?
I’m guessing the slide menu is the floating group you are referring to, or is it the one on top with the logo? If it is the slide menu then you will need to provide more information before anyone can help. Is it the Slider menu plugin or did you build it yourself? How are the icons populated - static or dynamic? Are the icons inside a group (below the floating group level) and is it set to collapse? You will need to provide enough information if you want help.
