How can I remove an item from a drop down list without changing the index of the other items?

I am modifying an existing application.
I want to have the least impact with the hole function of the website.
I need to remove the item in index 0 of my dropdownlist.
The problem is that the next item that will be added need to get index 1.
I think in leaving the item and hiding it but i do not know if this is possible.
Also I am thinking in remove the item from the list and set the start index in 1 instead of 0.
