How can I create a Html Helper like Html.BeginForm

I have an Extension Method that verifies if the user is able to see a portion of the webpage, based on a Role.

If I simple remove the content, this brings me more work as all the missing forms will not be correctly registered upon save and I have to deal with this behavior by modifying all my code, so I thought why not just use display:none; attribute?

I would like to have something like:

@using(Html.RoleAccess(currentUser, RoleAccessType.Content_General_Website))
{
    ...
}

and that this would write something like:

<div class="role_Content_General_Website" style="display:none;">
    ...
</div>

or use display:block; if the user has access...

I can create a simple HtmlHelper but how do I write one that also outputs the ending </div>?

public static string RoleAccess(
         this HtmlHelper helper, 
         UserInfo user, 
         RoleAccessType role)
{
   return 
       String.Format(
            "<div class='role_{0}' style='display:{1}'>", 
            role.ToString(), user.HasAccess(role));
}
