Pass data from array to multiple input box using gravity form in wordpress

I have made a website in wordpress. It has couple of forms which has input box depending on number of elements in the array. If the array has 2 dimensional array and each array has 2 values, then I need to add 2 x 2 input box with default values taken from the array.

I need to use gravity form.

Thanks in advance
