responsive

问题 Is there a way to achieve the following behavior in css/html : Please note the green side bar has not to be responsive but I cannot give it a fixed width with width: XX px; because it can contain more or less elements, so no idea of XX in advance.

问题 The toggle button appears in mobile view but it's not clickable. In angular appDropdown is used to define a drop down button. Is there a similar approach to fix the toggle button?
