How to show back button?

Hi again,

I can’t see the back button in the sub-menu:

    const config = new TelegrafInlineMenu("Configuration")
    config.setCommand('config');

    //Available languages
    const locales = new TelegrafInlineMenu("Locales");
    locales.simpleButton("italian", 'SET_LOCALE_IT', {
        doFunc: async ctx => settingsController.SetLocale(ctx, bot)
    });
    locales.simpleButton("english", 'SET_LOCALE_EN', {
        doFunc: async ctx => settingsController.SetLocale(ctx, bot)
    });

    config.submenu("Set locale", 's', locales);
    bot.use(config.init({
        backButtonText: "back...",
        mainMenuButtonText: "Go to main menu",
    }));

When I press on Set Locale I get:

• Italian
• English
• Go to main menu

but the back button missing… what I did wrong?

Thanks in advnance

The init is only required once per menu “tree”: Having two separate menus you need to init both. If one is a submenu of the other one, you only need to init it once.

- main
- config
→ Init both


- main
  - config
→ Init only main

And to your other question: Commands can be on every menu wherever they are in a menu tree. So this is possible:

const mainmenu = new TelegrafInlineMenu(…)
mainmenu.setCommand('start')

const submenu = new TelegrafInlineMenu(…)
submenu.setCommand('foo')
mainmenu.submenu(…, submenu)

bot.init(mainmenu.init(…))

This way you can either use /start and go to the submenu with a button or use /config (as a shortcut). This is especially handy for things like /help or /settings.
