It looks like you're new here. If you want to get involved, click one of these buttons!
How do you arrange items in rows like in the "example_1_TAo item" in "QTI Example Test"? No matter what I do I can only position new interactions above or below existing ones.
It does require a bit of fiddling: when dragging an interaction on the canvas, move it on top of the interaction you want to put it next to and then move to the left or right and keep it steady until a marker drops down, then release.
You can also resize the interaction up-front to make room for the new one, then drag it in the empty space and release.
Just let us know if this worked for you.
