Mark an element as valid drag destination.<\/p>\n

Use this tag together with scomp#draggable<\/code><\/a> to implement drag & drop. Elements that are marked as\ndroppable can receive drops of draggable elements. Drag & drop generates dragdrop events that are sent to the\ncontroller<\/a> or the delegate<\/a>.<\/p>\n

For example:<\/p>\n

<div id="dropzone">Drop your stuff here<\/div>\n{% droppable id="dropzone" tag="drop-tag" %}\n<\/code><\/pre>\n
Now draggable elements can de dropped onto the div with id “dropzone”. When a draggable is dropped then event\/2<\/code> of\nthe controller or delegate Erlang module is called signaling the drop (and also the drag to the module receiving the\ndraggable events):<\/p>\n
event({drop, Drag, Drop}, Context).\n<\/code><\/pre>\n
Where both Drag and Drop are #dragdrop<\/code> records:<\/p>\n
-record(dragdrop, {tag, delegate, id}).\n<\/code><\/pre>\n
The droppable tag accepts the following arguments:<\/p>\n
Argument<\/th>Description<\/th>Example<\/th><\/tr><\/thead>
id<\/code><\/td>The id of the element that will accept drops of draggables.<\/td>id="dropzone"<\/code><\/td><\/tr>
tag<\/code><\/td>The tag of the droppable that is sent as part of the drag and drop events. This can be any value, including a tuple.<\/td>tag={subject id=123}<\/code><\/td><\/tr>
active<\/code><\/td>The droppable will have this CSS class added when there is an acceptable draggable being dragged.<\/td>active="draghere"<\/code><\/td><\/tr>
hover<\/code><\/td>The droppable will have this CSS class added when there is an acceptable draggable hovering over it.<\/td>hover="dropnow"<\/code><\/td><\/tr>
accept<\/code><\/td>The group the droppable accepts. See the group argument of the draggable. A droppable can accept multiple groups, just repeat the accept argument.<\/td>accept="edges"<\/code><\/td><\/tr>
