How to remove the selected option in select tag?

I want to create a dropdown in such a way that on click of a button new dropdown is created but it should not show the selected option of the previous dropdown. I am able to create the dropdowns on button click but I can't figure out how to not show selected options of previous dropdowns.
Simply create an Array and map all your dropdowns from that. And in onClick function of button simply pop or modify the array element. I hope you got it. Feel feel to ask doubts and for more please update the source code.

Angularjs editable drop down in ng-repeat

I have a table made out of div tags with an ng-repeat to populate the divs from an array. I want to be able to make one of the div options an editable dropdown where the default option is a value stored from the array and the rest of the elements are loaded from another array. When a user selects an element from the drop down, the default option is then changed to whatever they selected. Does anything exist for this?
