wider space in drag text

Hi everybody:

Is there any possibility of making the blue space for the drag text wider for a longer sentence with longer words?

I would like to make some excercises where students have to drag the second part of the sentence and I would really like the whole sentence to be shown when they have completed the excercise.

Thank you very much in advance for your help and to the developers for all the work.

Cheers,

Teresa
