Add "select other" in the UI interface

Hello - I have minimal selected as the appearance for my question responses when its select multiple. I want to include an other to select other that then opens a text box to fill in what that “other” was. Please advise!

@ket5128, maybe this support article User-Specified “Other” Responses for Multiple-Choice Question should help you solve your issue.

Hi! this is helpful for the UI- thanks! If I want to make the same edit (adding an other option and automatic fill in the blank for that other) to the survey in the xls edit, how do I do that?

Sorry, I did not quite understand this issue. Could you kindly explain it again (maybe with examples if possible)?
