Readme
Angular directives that allow you to build sortable lists with the native HTML5 drag & drop API. The directives can also be nested to bring drag & drop to your WYSIWYG editor, your tree, or whatever fancy structure you are building.
This library is inspired by the https://github.com/marceljuenemann/angular-drag-and-drop-lists library which was written in AngularJS.

}
dndObject

CSS classes
dndDragging
This class will be added to the element while the element is being dragged. It will affect both the element you see while dragging and the source element that stays at it's position. Do not try to hide the source element with this class, because that will abort the drag operation.dndDraggingSource
This class will be added to the element after the drag operation was started, meaning it only affects the original element that is still at it's source position, and not the "element" that the user is dragging with his mouse pointerDrag List Inputs
dndList
Required attribute. Signifies that this list is part of the dndList. Can receive options on how to behave of the following type: interface DndListSettings {
allowedTypes: string[];
effectAllowed: string;
disabled: boolean;
externalSources: boolean;
horizontal: boolean;
}
dndModel
Required attribute. The array that holds the objects
dndPlaceholder
An element that should be displayed as a placeholder before a drag.
Drag Element Outputs
dndDragOver
An event that fires when an element is dragged over a list
dndDrop
An event that fires when an element is dropped upon a list
dndInserted
An event that happens after a drop if the object was actually inserted
CSS classes
dndDragover
This class will be added to the list while an element is being dragged over the list.dndNoDrag attribute
Use the dndNoDrag
attribute inside of dndDraggable
elements to prevent them from starting drag operations. This is especially useful if you want to use input elements inside of dndDraggable
elements or create specific handle elements.
dndHandle attribute
Use the dndHandle
directive within a dndNoDrag
element in order to allow dragging of that element after all. Therefore, by combining dndNoDrag
and dndHandle
you can allow dndDraggable
elements to only be dragged via specific handle elements.
