Drag and Drop Doesn't Work Within the Editor

[gregory-bretall]

Prelude

A customer noted to us that users are unable to drag and drop text or images internally in AlloyEditor. I verified that this is not only the case in the portal but on alloyeditor.com as well.

Issue

You cannot internally drag and drop text or images within AlloyEditor.

Steps to Reproduce :

1. Content -> Blogs -> Add Blog Entry
2. Upload an image to the blog post content
3. Write text to the body content
4. Attempt to drag image in between some words

Expected Results: The image is moved to the location the cursor indicates.

Actual Results: The cursor properly traces where you will 'drop' the image but on mouse up nothing happens. The image is not moved.

Solution

I made it so the preventDefault is only fired by AlloyEditor's dragdrop function when we need to specifically override the behavior, otherwise the default CKEditor dragDrop should be use.

Test

Tested on Chrome, Firefox, MS Edge, and IE11.
