Can someone please please please help me with this.  I have been searching for days and nobody seems to have the answer!

My store URL is and I am using the SUPPLY theme.

My company sells ready to eat meals and I sometimes have 2 variants for my products (choice of side and portion size).  I currently have a dropdown for the choice of sides but I would like to have a second dropdown just below it with the portion size. 

I am also trying to add a quantity selector with a + and - on each side just under the Add to Cart button.  I'm also trying to replace the current quantity selector on the cart page with a + and - selector.

I am pretty good with the shopify code so if someone can please give me the code and tell me where to paste it or any required steps to achieve this!

thank you!
