With our Javascript class FramelixPopup you can create containers that are attached to a
            element.
            It will stay there, flips automatically when scrolling comes to the edges of the popup, and have other cool
            features. The most obvious example of this is "Tooltip" (Hover
                this to see what we mean).
            
            In Framelix we us this, well, to show tooltips and for several other features like date picker, select
            dropdowns, etc...
