For creating a matching exercise you basically create a "Drag & Drop" cloze test. The only difference is that you choose "Matching" as the "mode".
First click on Create a Cloze Test / Matching Exercise, then enter your items (each pair on a new line) and mark (Create a Gap Word) of all the items you want the user to select. Choose "Matching" as the mode. It works the same as "Drag & Drop", except that all boxes are the same length.
