Description

The sortable lists can be used for horizontal and vertical ordering of list elements. The key element of using a sortable list is to provide drag handles to list items. These can be included using the core drag_handle template.

Source files

  • /lib/amd/src/sortable_lists.js
  • /lib/templates/drag_handle.mustache

Usage

The sortable list AMD module can be loaded in your template or via a amd init call. The list to be sorted is passed as the first argument to

// Default config, this variable is optional.
var config = {
    targetListSelector: null,
    moveHandlerSelector: '[data-drag-type=move]',
    isHorizontal: false,

};
new SortableList(domElement, config);
