Creating drag and drop interface

In eZ Platform, you can create a generic interface for drag and drop interactions reusable in many places.

First, prepare the HTML code structure that will be placed in a Twig template in the following way:

1
<div class="items-container" data-placeholder="HTML template for placeholder"></div>

Next, add options in the same Twig template or in a JavaScript code that comes with the template following the convention:

1
2
3
4
5
const draggable = new window.eZ.core.Draggable({
        itemsContainer: HTMLElement of .items-container,
        selectorItem: String,
        selectorPlaceholder: String,
});

For more information on creating Twig templates, see Templating basics.
