Draggable snap to selector

[gaggo]

Hi there, just got a club license to use the amazing ThrowPropsPlugin in combination with `draggable` and `type`:`scroll`. Now I would very much like an option to make the scrolling snap to certain elements, if flicked. Is there an option or approach for this?

Hi @gaggo

 

With the scrollTo plugin, you can scroll to an element ID, but the snap is going to need a number. If all the elements are the same size, it would be pretty easy to use a function and snap to a value, but I'm assuming the elements won't be the same size. I think a fairly easy approach would be to loop through your elements and get their offsetTop distance and create your snap array from those values. Maybe something like this?

Others may have additional suggestions, but that's the first thing that came to my mind. Happy tweening.

Hi Craig, ok thank you, I think in this case I will have to write a callback function for the snap property and determine which element is closest to the value. Thanks again for your hints!
