| === Summary ===
| |
| Drag and drop is an interaction technique involving either a mouse or touch enabled device where content is click and dragged from it's original position into a new position to permanently change the position of the element in the page. Unless care is taken, this interaction is not possible for users not using a mouse or touch interface (this could be a screen reader, or someone may have a motor impairment). Note: providing a non-javascript alternative for this interaction is not sufficient to make this accessible (javascript enabled != can use a mouse).

| === How this applies to Moodle === | |
| Keyboard navigation for drag and drop has been built into the Moodle yui module moodle-core-dragdrop. If you are implementing drag and drop in Moodle - use it - don't roll your own. Second - if you are using drag and drop in Moodle - you must use obvious "grab handles" which is a standard element used to initiate the drag and drop. Get a grab handle with M.core.dragdrop.get_drag_handle() (which will return a Y.Node with an image of a grab handle and event listeners already setup).
| |
| | |
| The way this works with M.core.dragdrop is that pressing enter on the drag handle will open list of valid drop targets for the drag with all the correct aria attributes.

| You need to alert the user of a visual changes. For example, if you collapsed a column from a table you would want to alert the user of the change.
