Generate Dynamic script with banner dimensions in an array from Sling model/HTL

Hi All,

We have a requirement to append the banner dimensions in an array format to generate the script encoded in HTL .Here in the script , the size mapping should be formed from the input given in the multi field item.

sizeMapping: [

[[x, y], [[a, b], [e, f]]],

[[z ,x], [a, b]],

[[y, z], [[e, f], [c, d]]],

],

sizes: [

[a, b],

[e, f],

[c, d],

],

[x, y],[z ,x],[y, z]-Breakpoint (first multi field values)

[a, b], [e, f],[c, d]-BannerSizeDimensions(nested multi field values)

So , size mapping should be formed in the combination of single breakpoint(highlighted) and multiple banner size dimensions as above in the array format .Also ,sizes should be formed from the unique values present in the banner size dimensions input as above.Could you please help me on how to achieve this array formatting in the script through sling model/HTL.

Thanks in Advance!
