Cancel drag

[marcosrocha85]

I'm trying to cancel a drag event in order to prevent moving cards on a automatic board, but when I call jkanban.drake.cancel(true) the dragula raises an exception saying "el is null" on touchy function. Do you have any suggestion to implement a "beforeDrag" event in order to validate if a card can be moved? I'm intended to develop that on jKanban.

For those who want do that outside jKanban, you can do jkanban.drake.cancel(true) at dropEl event. For example:

jkanban = new jKanban({
...
dropEl: function(el, target, source, sibling) {
    if (myValidationOfCanDrag) {
        jkanban.drake.cancel(true);
    }
}
...
);

@riktar, Noticed that dropEl fires even when the property "dragTo" is set and the card is dropped on a target board that supposely shouldn't accept dragging from source board. Is it possible to get the "dragTo" of target at dropEl element?

Very close issue to #22

Noticed that dropEl fires even when the property "dragTo" is set and the card is dropped on a target board that supposely shouldn't accept dragging from source board.

Suggestion: Don't fire dropEl when the item is now allowed to receive elements from dragTo property.

I'm having the same issue. If I drop an item on a non-allowed target, the dropEl is still fired.

I think I'm going to use a custom drag validation, as @marcosrocha85 suggested.
