DnD support for PropertyList<T>

Hi all,

As you might know then PropertyList<T> is very powerfull. It is help us to easy to manage and organize a list of complex property data but the limitation as I am facing with is that it is not official support sorting via drag and drop (or atleast I don't know how to turn it on - although take hour to googling).

Drag and drop not working on product | Episerver Developer Commun

Then I digged a bit with javascript solution as below then its worked: (I am assumming that you already know about how to create your module via module.config, create your custom editor and map it to your property list property)

So here is our code: SortableCollectionEditor.js

    // dojo

    // EPi Framework

    // epi cms

    // epi commerce
    function (

        // EPi Framework

        // epi cms

        // epi commerce
    ) {
        return declare([CollectionEditor, _GridWithDropContainerMixin, _FocusableMixin], {
            // module:
            //      app/editors/sortablecollectioneditor
            // summary:
            //      Editor widget for support propertylist dnd 

            resources: { "drophere": "You can drop {content} here", "actions": { "content": "content" } },

            postMixInProperties: function () {
                // summary:
                //      Post mix in properties initialization.
                // description:
                //      Fullfills properties that needed to start up the widget.
                // tags:
                //      protected


                this.gridSettings.dndParams = lang.mixin(this.gridSettings.dndParams, {
                    _checkAcceptanceForItems: function (items, acceptedTypes) {
                        var types =, function (item) {

                        var flag = false;
                        for (var j = 0; j < types.length; ++j) {
                            if (types[j] in acceptedTypes) {
                                flag = !!acceptedTypes[types[j]];
                        return flag;

Hope that help!

Is this just because the modal background is greyed out? I did a blog about something similar a while ago using CSS

Hi Scott, actually the default one CollectionEditor (epi-cms/contentediting/editors/CollectionEditor) did not support this.

Hmmmn, strange I know when I posted the blog and removed the CSS overlay I could drag and drop blocks/media and such in the PropertyList at least at the time of writing

Ah, it is different, my workaround is for change item sort order inside the list (using DnD instead of move up/down, very anoying when you have a long list)

And by the way, I'm talking about generic one (CollectionEditor) but not CommerceMediaCollectionEditor.

Yes I'm just referring to a PropertyList not anything commerce. Okay I see, sort order, I thought you meant drag and drop as in from other panes. My bad :p

Do you have a version working in a setup without Commerce? (in my solution epi-ecf-ui/contentediting/editors/_GridWithDropContainerMixin is missing)
