Collidable

Collidable

When you use the collidable plugin you can specify which elements you can't drag over and it will freeze the mirror movement for you. These currently only work with Sortable, Swappable and Droppable.

This plugin is not included by default, so make sure to import it before using.

import { Plugins } from '@shopify/draggable';

import Collidable from '@shopify/draggable/lib/plugins/collidable';

const sortable = new Sortable(document.querySelectorAll('ul'), {
  draggable: 'li',
  collidables: '.other-list',

});

sortable.on('collidable:in', () => console.log('collidable:in'));

Plans

• Improving collision detection for mirror

Caveats

• Currently only bases collision based on mouse cursor and not mirror element
