Mixture of Select and MultiSelect

[siredmar]

Currently i am using this library for a little interactive too that calls another menu and so on. This means i need to navigate forward and backward my menu structure. The forward part is pretty straight forward, but backwards is not. For a normal Select it is trivial by defining an "Back" option in the survey and looking at the response. For the MultiSelect however currently i am adding the "Back" manually. But this "Back" element behaves just like all other. I have to select it via the space on my keyboard to leave the menu.

Therefore i am looking for some sort of a mixture of MultiSelect and Select It could look like this:

? Choose [Use arrows to move, enter to select, type to filter]
> [ ] Watermelons
  [ ] Bananas
  [ ] Tequila
  Select All
  Exit

Is this already possible?

@siredmar I implemented the improvement proposed by your issue, which will also meet my needs.

@chiaretto this solves the 'select all' part msntuoned in my example above. This is great, but that's not what i asked for Initialy. I need to be able to chain several multiselects and be able to exit each of them without selecting anything from the list.

@siredmar But that is already possible. To exit without selecting, just press Enter without selecting anything. To link more than one, just follow the example below.

package main
import (
    "fmt"
    "strings"

    survey "github.com/AlecAivazis/survey/v2"
)

// the questions to ask
var multiQs = []*survey.Question{
    {
        Name: "country1",
        Prompt: &survey.MultiSelect{
            Message: "First Country :",
            Options: []string{
                "Afghanistan",
                "Åland Islands",
                "Albania",

    },{

        Prompt: &survey.MultiSelect{

func main() {
    answers := []string{}

    // ask the question
    err := survey.Ask(multiQs, &answers)

    if err != nil {
        fmt.Println(err.Error())
        return
    }
    // print the answers
    fmt.Printf("Your chose: %s\n", strings.Join(answers, ", "))
