Using a frontendmodule within your own module

Let’s imagine you created a login (frontend module) in contao and you want to output that in your own module. There’s a method called getFrontendModule which accepts the ID of a frontend module:

Assuming the login-module has id 9:

        // in your class
        $this->Template->login = $this->getFrontendModule(9);

and within your template:

 <?php echo $this->login; ?>

Simple, eh? Would have saved me days if I would have known this earlier.
