How to add dynamic voices?

I have this sub-menu:

const projects = new TelegrafInlineMenu(ctx => ctx.i18n.t('projectsHandler'));
projects.setCommand('myprojects');
main.submenu(ctx => ctx.i18n.t('projectsHandler'), 'p', projects);

essentially when I type the command myprojects the menu is displayed, and this works well. Now, I need to show in this menu all the projects store inside my MongoDB database, so essentially when I write /myprojects the menu must be built dynamically.

Could you tell me how can I add dynamic voices?

Kind regards.

Oh, I meant that differently. Sorry for not being clear there. Thats what I meant with textFunc:

menu.selectSubmenu(…, getOptions, p, {
  textFunc: (ctx, key) => {…}
}

If you like your way and want to continue it, you can return a dictionary like the following example. Its nice to have but tended to messy code in my experience.

{
  a: 'AAA',
  b: 'BBB'
  c: 'I like trains'
}

which would require this code:

    let objects = {};
    projects.forEach(p => {
        objects[p._id] = p.name;
    });

If I understand your code correctly you want to have this menu structure:

• main
  • projects
    • p (for each option)

In this case main.submenu(…, projects) is still what you wanted? Your last example has two selectSubmenu calls which you probably don’t want?

To your question 1: you can set the columns on a menu.select(). 1 column → 1 entry per row.

To your question 2: The menu p which handles the specific project can read it from ctx.match. Most likely ctx.match[1] but it can be different depending on the menu structure.

Maybe its helpful to explain the purpose of each method:

• submenu takes a submenu and one button leading to it
• select takes multiple options which can be used to select something out of multiple entries.
• selectSubmenu combines both: you can pick which option you want to handle in the submenu

const projects = new …
projects.setCommand('myprojects')

const p = new TelegrafInlineMenu(ctx => ctx.match[1])
projects.selectSubmenu('pro', ctx => loadProjectsForContext(ctx), p)

main.select(…, projects)
