Dynamically insert a form view into a template view

[eluser]imcl[/eluser]
Haven't been able to figure this out yet:

I have a view file (main_view.php) which I use as my template.

It has a left-sided div for the menu, and another div for content:

Code:

<td width="200">
                    <div class="">
                        &lt;?= $menu ?&gt;
                        </div>
</td>

<td width="700">
                    <div class="">
                        &lt;?= $content ?&gt;
                        </div>
</td>

Say the left menu shows the following links:

Code:

- Update email
- Update Password
- Update Profile

How do I make different forms appear in the <?= $content?> div when each menu item is clicked?

I have no idea how to pass the following code to <?= $content?> (this is the change_email_form view from Tank_auth).

Any suggestions are much appreciated!

Code:

<?php
$password = array(
    'name'    => 'password',
    'id'    => 'password',
    'size'    => 30,
);
$email = array(
    'name'    => 'email',
    'id'    => 'email',
    'value'    => set_value('email'),
    'maxlength'    => 80,
    'size'    => 30,
);
?>
<?php echo form_open($this->uri->uri_string()); ?>
<table>
    <tr>
        <td>&lt;?php echo form_label('Password', $password['id']); ?&gt;</td>
        <td>&lt;?php echo form_password($password); ?&gt;</td>
        <td style="color: red;">&lt;?php echo form_error($password['name']); ?&gt;&lt;?php echo isset($errors[$password['name']])?$errors[$password['name']]:''; ?&gt;</td>
    </tr>
    <tr>
        <td>&lt;?php echo form_label('New email address', $email['id']); ?&gt;</td>
        <td>&lt;?php echo form_input($email); ?&gt;</td>
        <td style="color: red;">&lt;?php echo form_error($email['name']); ?&gt;&lt;?php echo isset($errors[$email['name']])?$errors[$email['name']]:''; ?&gt;</td>
    </tr>
</table>
&lt;?php echo form_submit('change', 'Send confirmation email'); ?&gt;
&lt;?php echo form_close(); ?&gt;
