Dragging names to objects in an image

Hello,
I want to make a vocabulary exercise with the option "Drag and drop", in this case, with an image with the objects of a "living room". When I drag a word, for example "the lamp", I can see the place where I have to put the word because some intermittent lines appear, but I don't want to. Can you add the option to make disappear these lines or create another type of exercise to do this?
See this link to understand what I mean. (The intermittent line wouldn't appear in the exercise)

Another issue: Adding a box with diacritical marks to do Spanish grammar exercices.
When I build grammar exercises in Spanish, it would be very useful to add a box with diacritical
marks as: á, é, í, ó, ú, ü, ñ, ¿ ? ¡ ! so that user can choose the correct letter independently of the type of keyboard.
See an example in this website:

Thank you.
