Drag And Drop

I experienced the html5 drag and drop api to be buggy and inconsistend across browsers, but all building blocks to roll a pure-elm version exist: mouseover and mouseleave events, a subscription to mouseup events and voila.

However, I reuse the dragstart event (from the html5 api), so that draggable elements can still receive onclick events.

Demo

An example can be tested out by cloning the repo locally and running elm-reactor:

$ git clone https://github.com/matheus23/elm-drag-and-drop.git
$ elm-package install
$ elm-reactor

Now open a webbrowser and go to localhost:8000/src/Example.elm.

Disclaimer

This package is still under construction and documentation is limited. This may change in the future when the API does not change that much anymore.

'Low' level API

Can be found in the module DragAndDrop. It is used to implement a higher level API for reorderable lists.

'High' level API

Can be found in the module DragAndDrop.ReorderList together with DragAndDrop.Divider. Can be used to implement a list of things that can be reordered by dragging its elements.
