NOTE.- See attached screen shot to view the different rendering with JS enabled/disabled. With JS disabled it would look nicer if the items were ordered (and the dropdown list numbers ranged from 1 to ...n). But I do not know how to do it and - given the low number of people who surf the Internet with JS disabled anyway - I do not think it worthwhile to spend time on it.

.draglist.inline {
 line-height:2.2em;
}

It works (see screenshots #2 and #4). However, you might consider adding this extra height to the item boxes directly in your questiontype.php file.

PS 1.- Note that in any case the longish text items may overflow over to the next line. Personally I do not find this a problem.

PS 2.- With text items displayed over more than one line, the drag & drop will only work from the beginning part of the item. For example, in #4, although the drag & drop cursor will appear when hovering over "Source software package designed etc." it will not be possible to carry out a drop & drag action there; drop & drag will only work on the "a free, Open" part. It would be more user-friendly not to display the drag & drop cursor on an item part which is not draggable, but this might entail complex programming.

Found a bug in edit mode of the drag & drop question when you want to create a question with more than 6 items in it. For exemple create a question with 7 items in it.

• Create a new "ordering" type question.
• enter question name and question text
• enter 3 items
• click on Add more items button
• enter items 4 to 6
• click on Add more items button
• enter item #7
• click on the Save changes button
• you can't save your question!
  

The only way to create more than 6 items is to create a question with 3 or 6 items only, save it, then edit it, add the extra items, and save it again.
