How to make a Custom Variant Picker Section (DAWN THEME)?

[Karan_huedlife]

I want to make a custom Variant picker for my website "https://puretive.co/products/gut-repair" which looks something like this 

Sample website url (https://thegoodbug.com/products/metabolically-lean-weight-management?variant=43748465148129)

And currently i have a default variant picker which looks like this

Page in above picture (https://puretive.co/products/gut-repair) I've tried a lot of things but nothing seems to work. Can anyone help me implement this? If not then some other way where we can show how much % the buyer is saving ON THE VARIANT BUTTON ITSELF if he buys a combo of 2 Items. 
Thanks in advance 🙂
