I want to like this below if anyone can share with Screenshot/Video.

Product Name = Fine Flour A
This Product have 10KG, 15KG, 20KG, 25KG bundles.
So when I select Fine Flour A in invoice then I can select which bundle I want to sale and next for quantity.
Example
      Product ------------Weight/Bundle-------Qty----------Rate--------Amount
1:- Fine Flour A ------------- 10KG ------------ 10 ---------- 90 -------- 900
2:- Fine Flour A ------------- 15KG ------------ 8 ---------- 110 -------- 880
3:- Fine Flour A ------------- 20KG ------------ 15 ---------- 120 -------- 1800
4:- Fine Flour A ------------- 25KG ------------ 12 ---------- 140 -------- 1680

And it can reduce total quantity 100KG for 1st product, 120KG for 2nd product.
