Bending (or breaking) the DataGrid form layout options

[SparkOut]

Is there a way of making a DG form template that can be laid out in a repetitive tile pattern? ie, side by side until a wraparound point where a new row of form "tiles" will begin?
I have been fudging with repeated elements in a single form template and it's sort of working but a big headache to layout and resize, and the dgData needs to be mashed to get this to populate correctly:
theDataA[1]["image"]
theDataA[2]["image"]
theDataA[3]["image"]
theDataA[4]["image"]
theDataA[5]["image"]
theDataA[6]["image"]
needs to be rearranged to
theDataA[1]["image1"]
theDataA[1]["image2"]
theDataA[1]["image3"]
theDataA[2]["image1"]
theDataA[2]["image2"]
theDataA[2]["image3"]
(etc etc)
