Nested Loop with parser template

[eluser]giovannidc[/eluser]
Hey,

Was wondering if anyone had a solution to creating a nested loop with the template parser:

Code:

{users_details}
<input type="text" name="displayname" value="{user_displayname}"/>
<input type="text" name="email" value="{user_email}"/>

<select name="company">             {companies}
<option value="{company_id}">{company_name}</option>
{/companies}        
</select>

{/users_details}

The above code does not display the way I want it. Instead of getting:

Code:

<option value="1">Microsoft</option>

I'm getting

Code:

{companies}
<option value="{company_id}">{company_name}</option>
{/companies}

So my assumption is that nested parsing is not allowed?
