WooCommerce – Muliple options on a dropdown menu with one price

Hello, I have a question for the WP development community.

I would like a user to select 5 options in a dropdown menu with only one price. If a user increases the qty value, the price only increases higher from the 5 selected options.

I have tried different methods but can’t seem to create a solution. I have started development, but the checkout page dropdown options appear with individual pricing. I need it to be one price with selecting 5 selects.

You may click on the link provided, scroll to the bottom of the page to the “Mix N Match” section to see what I have started to develop.

Thank you for the help in advance.
