Is there a way to make a tab completer for sub-commands for skript?
https://cdn.discordapp.com/attachme...9910/Screen_Shot_2020-07-11_at_9.21.24_AM.png like this but for sub-commands. I'm trying to make a /gm command and want all the tab complete to be the gamemodes

command /gm <Gamemode>:
  permission: op
  trigger:
    set gamemode of player to arg-1

code for the command so far, just need the subcommand thing

If I remember correctly, it was something like this:

on chat tab complete:
    event-string is "/gm":
        add "creative" to {_gamemode::*}
        add "survival" to {_gamemode::*}
        add "adventure" to {_gamemode::*}
        add "spectator" to {_gamemode::*}
        loop {_gamemode::*}:
            add loop-value to completions

You need MundoSk to do this.
