PowerShell Menu – Template .PS1 File

Hi.

Couldn’t find a batch menu demo that contained more than two layers in their example.
The template includes a main menu window, a sub-menu, and options to expand the console as deep as you want to go.

The menu and sub-menu loops until you select a valid entry from the displayed options and exit the script gracefully from the main menu.
