A menu is a set of interactive buttons that is displayed beneath a message. It uses an inline keyboard for that, so in a sense, a menu is just an inline keyboard spiced up with interactivity (such as navigation between multiple pages).
// Creating a simple menu
const menu = new Menu('my-menu-identifier')
.text('A', ctx => ctx.reply('You pressed A!')).row()
.text('B', ctx => ctx.reply('You pressed B!'))
// Make it interactive
bot.use(menu)
bot.command('start', async ctx => {
// Send the menu:
await ctx.reply('Check out this menu:', {
reply_markup: menu
})
})
