How to create an 'Other...' option
A common scenario inside forms is the case of an 'Other...' option as part of a list of options, giving the respondent the possibility to enter a missing option. Let's see how to achieve this.
The idea is to use a simple branch based on a match on the 'Other' option. In case a respondent selects that option, a follow-up question is shown. In most cases this will be a text input field, so the respondent can enter its own answer.
More logic possibilities
The logic described in this article is just a simple example of a branch, but the possibilities of branches are limitless, as you can see in this article.
We have made a video tutorial on how to add a branch for an 'Other...' option. It's a tutorial on simple logic, which shows what steps to take to get this done.
