It is possible to use the "Drag and drop into text" for a "jumble" activity. That is the good news!

For a "word jumble", simply replace all the words in a sentence with appropriate [[n]] placeholders.
However, if a certain word has more than one occurrence in the sentence, it needs to be marked as "infinite", in order to be used more than once.

But, this does not work if all choices are marked as belonging to the same group.

One solution is to put those words which need to be marked as "infinite" in the same group, different from the group that all the other words (non-repeated) belong to. However, this "gives away" the repeated words, especially if there is only one of them, as in the example that follows.

The "groups" feature is quite useful for marking certain words belonging to a grammatical or semantic category, of course, but not in the case at hand.

"the black cat sat on the white mat"
[[1]] [[2]] [[3]] [[4]] [[5]] [[1]] [[6]] [[7]]
case 1.- "the" marked as infinite; all choices in group 1 -> does not work; well, it's possible to give a correct, accepted answer, but an extra "the" choice gets displayed!
case 2.- "the" marked as infinite; "the" choice in group 1; all other choices in group 2 -> works, but gives away "the" place in sentence

Question: should it not be possible to make case #1 work?
