As I am new to react js. I have a question in concatenation of two switch cases. I mean for example if I select the cotton in dropdown list from case 1 and that should automatically take the value from the case 2 as white color. For example:

case "select1":
let options=[
            "White",
            "Blue",
            "Aqua",
            "Aquamarine",
            "Azure",
            "Beige"]

case "select2":
let option=[
           "cotton fabric",
            "silk fabric",
             ....]
