I am having some trouble trying to figure out how to implement a Drop down list with some sort of "reverse validation."
What I want to do is have the user enter a phone number or many phone numbers in a box.
user enters the number 555-555-555 in the box
he now has the possibility of entering in more phone numbers in that same box by clicking the down arrow and selecting "add another number"
Once the user clicks "add another number," the text box prompts the user "enter another number."
The user can then click other and "add another number"
The final result is something like so, the line diving what is visible on the page and what is on the dropdown
