Basically i have 8 option value. I want to randomly generate the value of each option with one click of the generate button. any suggestion? Thank you in advance

Algorithm:

1. First Getting the current Dropdownlist
2. Making the current dropdown item shuffled
3. Removing current dowpdown item from existing node
4. Populating the new dropdown value with random item

Hope it would guide you accordingly what you are trying to implement.
