Why?

Because apparently there was nothing that does not require jquery out there.
This is better than https://jqueryui.com/selectable/ or https://jqueryui.com/draggable/ and has no dependencies. It is used in multiple professional rich interface applications, i.e. to have a file management system. The user can select files to organize them and change their metadata, with this plugin our users could select multiple files and perform batch/bulk-operations (applying changes to multiple files at once). Another example is a huge, graphical cloud hosting manager with millions of active users. Users can select multiple servers, storages, etc. on an art-board to perform multi-operations, re-organize them, move them on the UI or batch-delete. We’re running it since January 18' it’s super helpful and very stable, let’s keep it that way. I can easily think of dozens other use-cases. I’m really keen to know how you use it in your projects, please let us know.

Installation

Read the Getting Started.

NPM

npm install --save dragselect

Yarn

yarn add dragselect

Global

You can still download the file (minified) and add it to your document:

<script src="https://unpkg.com/dragselect@latest/dist/ds.min.js"></script>

Note: if you are using <script type=module you can use the DragSelect.esm.js or ds.esm.min.js files as they include export default DragSelect

We don’t recommend the direct linking for production set-up. Please use npm if you can.

That's it, you're ready to rock!

Of course you can also just include the code within your code and bundle it to save a request.

DragSelect supports module.exports, AMD Modules with define, es6 modules with .esm versions and has a fallback to global namespace for maximum out of the box support.

Usage

Now in your JavaScript you can simply pass elements to the function like so:

Simple

Read the Simple Usage Guide

The simplest possible usage.
Choose which elements can be selected:

new DragSelect({
  selectables: document.getElementsByClassName("selectable-nodes"),
});

Find a live example in the Guide

Within a Scroll-Able Area

Read the Area Guide

Here the selection is constrained. You can only use the selection/drag inside of the area container:

new DragSelect({
  selectables: document.getElementsByClassName("selectable-nodes"),
  area: document.getElementById("area"),
});

Find a live example in the Area Guide

With DropZones

Read the DropZones Guide where you’ll also find a live example.

Extended

All options are optional. You could also just initiate the Dragselect by new DragSelect({}); without any option.

Find all possible properties and methods in the docs

Hint: you can also use the "shift", "ctrl" or "command" key to make multiple independent selections.

React

Accessibility (a11y)

DragSelect is accessible by default:

TLDR;
=> Your selectables should be buttons: <button type="button"></button>.
=> ArrowKeys are used for keyboard dragging.

Constructor Properties (Settings)

DragSelect is hyper customizable. Note, all properties are optional.

Moreover any setting can also be updated or added after the initialization, see post-initialization setting updates.

Post-Initialization Setting-Updates

Any setting can be updated/added after initialization by using the setSettings method. Here is an example updating the area and the selectables:

const ds = new DragSelect({})
ds.setSettings({
  selectables: document.getElementsByClassName('selectable-nodes'),
  area: document.getElementById('area')
})
