SortableEvent

event.from; // previous list
event.to; // list of currently placed drag element
event.node; // dragged element
event.nodes; // dragged elements
event.clone; // cloned element, all dnd operations are based on cloned element and do not alter the source dom(node).
event.clones; // cloned elements, there is a value only in the `pull: clone` after moving to a another list.
event.target; // drop element
event.oldIndex; // old index within parent. `-1`: element added from another list to the current list
event.newIndex; // new index within parent. `-1`: element has been removed from the current list
event.event; // TouchEvent | MouseEvent
event.pullMode; // Pull mode if dragging into another sortable.
event.relative; // Position of the drop element relative to the drag element after swap is complete.
event.revertDrag; // revert draged element to initial position after moving to a another list in `pull: 'clone'` & `revertDrag: true`.
event.backToOrigin; // dragged element go back to the original list in `pull: 'clone'`.

SelectEvent

event.event; // TouchEvent | MouseEvent
event.index; // index within parent
event.node; // dragged element
event.from; // list container

Methods

let sortable = new Sortable(el);

// Manually clear all the state of the component, using this method the component will not be draggable
sortable.destroy();

// Get or set the option value, depending on whether the `value` is passed in
sortable.option(key, value?);

// Selects the provided multi-drag item
sortable.select(element);

// Deselects the provided multi-drag item
sortable.deselect(element);

// Get the selected elements in the list, the return value is available in the case of `multiple`
sortable.getSelectedElements();
