.minY

Number - When bounds are applied, minY refers to the minimum “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", minY would correlate with y transform translation, as in the CSS transform: translateY(...). For type: "top,left", the Draggable’s minY 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.
