Multistep or Variations

Hello everyone,

Im hoping to get some assistance with WooCommerce.

1. My first issue is I need a variation for a product in the form of a multiple selection box.

Ex. Let’s say I wanted to sell sandwich’s and the customer had allergies, well I’d want to list common allergies then have the end user be able to select all the allergies he may have so I dont make his sandwich with any ingredients that would cause him/her harm.

2. My Second issue is i’d like the customer to be able to add a custom selection to a variation.
Ex. Let’s say in the sandwich example the customer has an allergy to something not listed, I’d like to have a “add allergy” button of some sort that would had his/her restriction to the list of variations.

Is there a way to do this?
