Hi, I've found this neat piece of code from Jeffery and I wanted to make nested menus using this.

http://jdhitsolutions.com/blog/2011/12/friday-fun-a-powershell-console-menu/

The only problem is that in that sample code when user presses Q, the script ends, but in the nested menus, I just need it to leave the current loop. I've tried using Break (in the code below), but that doesn't do anything there. Exit/Return exits the whole script.

Any ideas?

Nested menu might look like this:

$menu1=@"
1 Item1
2 Item2
Q Quit
"@

$menu2=@"
1 Add
2 Remove
0 Exit to previous menu
"@


#Keep looping and running the menu until the user selects Q (or q).
Do {
    #use a Switch construct to take action depending on what menu choice is selected.
    Switch (Show-Menu $menu1 "Menu1" -clear) {
     "1" {
         Do {
             Switch (Show-menu $menu2 "Menu2" -clear) {
             "1" {
                 }
             "2" {
                 }
             "0" {Break}
            } #switch
          } #do
         While ($true)
         } #menu    
     "2" {}
     "Q" {Write-Host "End" -ForegroundColor Cyan
         Return
         }
     Default {Write-Warning "Wrong choice, try again"
              sleep -seconds 1}
    } #switch
} While ($True)

I'm curious to see Jeffery's answer, but in the mean time, this will work.


#Keep looping and running the menu until the user selects Q (or q).
Do {
    #use a Switch construct to take action depending on what menu choice is selected.
    $back = 1
    Switch (Show-Menu $menu1 "Menu1" -clear) {
     "1" {
         Do {
             Switch (Show-menu $menu2 "Menu2" -clear) {
             "1" {
                 }
             "2" {
                 }
             "0" {$back = 0}
            } #switch
          } #do
         While ($back)
         } #menu    
     "2" {}
     "Q" {Write-Host "End" -ForegroundColor Cyan
         Return
         }
     Default {Write-Warning "Wrong choice, try again"
              sleep -seconds 1}
    } #switch
} While ($True)
