agnostic-draggable

Most of UI developers that worked with web apps from 2008 to 2014 certainly used or at least searched for a library implementing Drag & Drop support. From all the libraries that were available within that period, jQuery UI was certainly one of the best choices.

Years later, most of the web applications are tied to frameworks or rendering libraries like Angular, Vue and React and keeping jQuery and jQuery UI as a dependency to these projects can be a headache. In fact, moving away from jQuery is something that many development teams have experienced after these frameworks came into the scene.

However, finding a good replacement for what jQuery UI used to offer in terms of drag/drop capabilities is not easy. If you are looking for a solution that is tied to your framework/library of choice, there are plenty of options for you. But if you are looking for a VanillaJS based and agnostic implementation of drag & drop, you can find yourself browsing for a couple of hours finding just a few consistent options.

Shopify/Draggable is a nice alternative, although it has some crucial behaviour changes compared with what jQuery UI used to offer. SortableJS offers something similar to what the jQuery UI`s Sortable widget offers. By looking at the examples, it seems to be even possible to mimic the behavior of the "connectToSortable" option of jQuery UI's Draggable widget, that allows an item to be dragged onto a list that has sort capabilities. Native Drag & Drop implementation from the browser? Forget it until it can support dragging an element using a cloned helper node. Furthermore, the API offered by the native implementation really sucks.

The solution? Translate the implementation of the Draggable, Droppable and Sortable widgets from jQuery UI into an agnostic, VanillaJS and ES6+ based library. Most of the options and features found in the original implementation by jQuery UI's team are here. The ones that were not translated/rewritten were just not part of the subset of features considered to be the most important ones. This doesn't mean that contributors cannot help finishing the task of bringing them in.

Usage and Documentation

Draggable

Enables dragging functionality on any DOM element. Move the Draggable element by clicking on it and dragging it anywhere within the viewport.

Elements modified or created will use the same CSS classes inherited from jQuery UI's implementation:

ui-draggable: the element being dragged
ui-draggable-handle: the handle of the draggable element. By default, each draggable is also a handle
ui-draggable-helper: the dragging helper

new Draggable(document.querySelector('#drag1'), null, {
	'drag:start': function (event) {
		event.cancel();
	}
});

Droppable

Transforms elements into droppables or drop zones. This means that elements controlled by a Draggable can be dropped into a Droppable if accepted by them.

Elements modified or created will use the same CSS classes inherited from jQuery UI's implementation:

ui-droppable: the droppable element
ui-droppable-active: identifies an active droppable element
ui-droppable-hover: used when the droppable has a draggable intersecting with it

Options

Name	Type	Default	Description
`accept`	`{String,Function}`	`*`	Controls which Draggable elements are accepted.
`disabled`	`{Boolean}`	null	Allows disabling the Droppable behaviour.

`tolerance`	`{String}`	`intersect`	Intersection mode between Draggables and Droppables.

`accept`

Type: String,Function
Default: *
Accepted values: a CSS selector or a function
Modifiable at runtime: yes

Controls which Draggable elements can be accepted by this Droppable. It can be a CSS selector that needs to match the accepted Draggables or a function that receives each dragging element and returns true if the element is accepted.

<div id="drop1">Drop Here</div>

<div id="drop1">Drop Here</div>

import { Draggable, Droppable } from 'agnostic-draggable';

new Draggable(document.querySelector('#drag1'), {

});

`tolerance`

Type: String

Accepted values: fit, intersect, pointer or touch
Modifiable at runtime: yes

Specifies which mode to use for testing whether a Draggable is hovering over a Droppable. The fit option requires the dragging element to overlap the droppable area entirely. The intersect option requires the dragging element to overlap the droppable area at 50% in both directions. The pointer requires the mouse pointer to overlap the droppable area. The touch requires the dragging element to overlap the droppable area in any amount or direction.

Sortable

Transforms elements that contains multiple child nodes in a way that these child nodes can be sorted by using the mouse.

Elements modified or created will use the same CSS classes inherited from jQuery UI's implementation:

ui-sortable: the element containing the sortable elements
ui-sortable-handle: the handle of each sortable item. By default, each sortable item is also a handle
