[NTG-context] Centered framed text in two columns

Dear All, I would like to vertically center a framed text in front of an item list, something like : - item - item - item my framed text - item - item I tried with two columns then by defining a paragraph but without success. I would also like the columns to have a fixed width like 70%-30% of the textwidth. Any hint ?
