获取输入字段数据以保存在选择选项值中

I have this dropdown list with different values. What i am trying to do is whenever I select other option, the hidden div with id=othertype show and I will type in input field and want to save that data but its not working. I can't use the same name attribute twice I know but I don't want a separate column just for other input. Is it possible to save the input value in same column as options? I want value of input field and not the value I am passing in other option which is other itself.I have this dropdown list with different values
