Erase Everything - How?

Hi, I'm playing around with terminal-kit and what I'm trying to do is to create a navigation. Once the users submits on a menu I want to rewrite everything and draw a new document. However the menu never gets removed from the screen.

you can use term.clear() or term.eraseDisplay() fo this things
Theres a code snippet for what you asked:

...
const menuOptions = {
    y: 1,
    style: term.inverse,
    selectedStyle: term.dim.blue.bgGreen,
    cancelable: true
};

function displayMenu() {
    term.clear();
    term.singleLineMenu(menuItems, menuOptions, function (error, response) {
        if (error) {
            term.red.bold('Error: %s\n', error);
            process.exit(1);
        }

        if (response.canceled) {
            term.red.bold('Menu canceled\n');
            process.exit();
        }

        // After selecting clear screen and write new content
        term.clear();

        switch (response.selectedText) {
            case 'Home':
                term.green('Welcome to the Home page!\n');
                break;
            case 'Settings':
                term.yellow('Here are the Settings.\n');
                break;
            case 'Profile':
                term.blue('This is your Profile.\n');
                break;
            case 'Exit':
                term.red('Exiting...\n');
                process.exit();
                break;
            default:
                term('Unknown selection.\n');
                break;
        }

        // after drawing new content return to the menu
        setTimeout(displayMenu, 2000); // after 2 secs show menu
    });
}

// show first menu
displayMenu();
