I have two lists. One is the 'Product' list and the other is the 'product description' list. There is a unique productId in the product list. Using jquery I have modified the Title column of the 'Product description list' and it is automatically populating the product Id. I want to create a lookup column in the 'product description list' which filters all the productId from the product list. The lookup column should by default select the value present in the title column of the product description' list. so that by referring to the lookup column I can auto-populate other column values from 'product list'.
