    In fact I've managed to include "blank answers" assigning the html code &nbsp to one of the items. It renders a blank square that can be dragged and dropped.

    Hi! The question type is great!
    Is there an upgrade to 3+ foreseen?
    Thank you!

    In Moodle 3.0+ this is a standard question type that comes as part of the main install.

    For mathematical and/or technical questions it would be very desirable if we could use LATeX code within the drag boxes. MathJAX works very well with Moodle, but in the draxboxes the code is not interpreted by MathJAX. I suppose, after Javascript has created the dragboxes, would the MathJAX Hub have to be called again?

    If we want to implement this behavior into the "drag and drop text questions" ourselves, where in the source code would be the appropriate place?

    I could imagine to program my own question type "Drag Drop LATeX", which inherits from the existing D'n'D classes, but implements Javascript for MathJAX.

    I am very grateful for any information.

    Yours sincerely Achim

    In addition to my former comment. When adding following JS to the additional HTML Header Section: the LaTeX in my dragboxes is interpreted. And I can drag'n'drop the boxes. BUT, the dimensions of the dragboxes are those of the uninterpreted content!
    I think there is a race-condition between D'n'D javascript and MathJAX javascript.

    I had a glance at ddwtos.js. There is a method "initializer" which calls "set_padding_sizes_all()".
    My guess is, that, if LaTeX would be rendered before this method is called, everything should work fine.

    Could anyone assist me here? I think this could be helpful for everyone developing mathematical/technical content!

    Yours sincerly Achim

    Sorry, my jacascript in the former comment was removed. I called within window.onload the typesetting for mathjax hub.

    Right, the reason maths in drag items was disabled was because of that race condition, which we could not find a fix for at the time. It must be possible to fix, but someone has to work out how. It would certainly be good to allow maths etc. in drag items.

    I have also had several students in the last few days tell me that they can no longer drag text items. This has been since the upgrade to Moodle 3.9, although I don't know if that is the cause of it or not. I tested a quiz on my iPhone and found that I had the same problem. Using "Gapfill" to accomplish this same function seems to work as a suitable "replacement", but since drag and drop into text is now core .....

    This plugin has been part of standard Moodle for years. This is not a good place to discuss it.

    Hi, I want to use the Drag and Drop into text for a quiz, but how do I make it so if the student gets any of the drag to drop into text questions wrong the whole answer is wrong? An all or nothing type of question.

    If I have found something strange (or maybe I have done something incorrectly), HOW and WHERE can I give the feedback to find out the possible cause ... Thank you. @Tim Hunt and Developer.

    The quiz forum is a good place to start. https://moodle.org/mod/forum/view.php?id=737
