It is possible to create branching questions with inquirer?

Question

const employeeQuestion = [
    {
        type: "list",
        name: "employeeTitle",
        message: "What's the employee's title",
        choices: ["Engineer", "Intern"]

    },

    //when role is engineer is true, ask this question
    {
        when: input => {
            return input.role == "Engineer"
        },
        type: "input",
        name: "github",
        message: "Enter your github username:",
    },

    //when role is intern is true, ask this question
    {
        when: input => {
            return input.role == "Intern"
        },
        type: "input",
        name: "school",
        message: "What's the school you enrolled in ?",
    },

]

The idea is I want to utilize inquirer's when method so the question whether to ask about the user's github or school is dependent on the answer on the employee's title. But when i run node on the command line, the question asking for github / school never appeared. I wonder if I used the method wrong or if there are other alternatives.

inquirer's when method is definitely the correct one for this situation!

There are two possible reasons:

You are using input.role but never defining a role value in the answers hash. You need to refer to the name value from the earlier question, in this case, input.employeeTitle.

If reason 1 does not fix it, try expanding your function a bit. when needs to take in the answers hash as an input, then apply the conditional to that and explicitly return a Boolean. Ex.

{
     type: "input",
     name: "github",
     message: "Enter your github username:",
     when: (answers) => {
         if (answers.employeeTitle === "Engineer") {
             return true;
         }
}
