I’m a product owner trying to communicate clearly with developers

Let me know if this isn't an appropriate place, but I feel developers are the ones I should ask.

I am trying to ask my software developers at work for the following functionality in our system:

• I have a set of attributes describing cooking method type of a product. There can be up to 10 methods, and each needs to be their own individual attribute, but I don't want all 10 blank attributes showing if I only have 2 methods.
• I'd like for JUST the next blank one to be visible and the other attributes to be hidden until they are needed.

EXAMPLE

• It starts with 3 blank lines
  • Method 1 – ________
  • Method 2 – ________
  • Method 3 – ________
• I fill out 2 of them
  • Method 1 – Bake
  • Method 2 – Pan Fry
  • Method 3 – ________
• I add a 3rd method, and so a 4th blank field appears
  • Method 1 – Bake
  • Method 2 – Pan Fry
  • Method 3 – Deep Fry
  • Method 4 – ________

​

I realize I could just send them all this, and I probably will in the more formal writing of requirements, but I'm trying to talk about this on calls and I am hoping there is a phrase I can use to describe this type of listing. Any ideas?
