.maxY

Number - When bounds are applied, maxY refers to the maximum “legal” value of the horizontal property (either "y" or "top", depending on which type the Draggable is). This makes it easier to run your own custom logic inside the snap or callback function(s) if you so choose. So for a Draggable of type: "x,y", maxY would correlate with y transform translation, as in the CSS transform: translateY(...). For type: "top,left", the Draggable’s maxY would correlate with the CSS top value that’s applied. This is not the global coordinate - it is the inline CSS-related value applied to the element.
