Hello,
I have two data objects: one for Products, one for Features.

I want to show them in front-end as two tabs in a Tabset. So I created a Form in my controller class

class Product_Controller extends Page_Controller{
public static $allowed_actions = array('myForm');

public function myForm() {
// Create fields
$fields = new FieldList(
      new TabSet(
       $name = "TheTabSetName",
       new Tab(
          $title='Tab one',
    new HeaderField("A header"),
       new LiteralField("info from dataobject1.") // to keep it simple I replace the code with some place-holder texts
       ),
      new Tab(
    $title='Tab two',
    new HeaderField("A second header"),
    new LiteralField("info from dataobject2.")
      ))
);

return new Form($this, 'myForm', $fields);
}
}

And here it is my Product.ss file:
<div id="myform">
<h2>my form</h2>
$myForm
</div>
<div class="Content">

But it doesn't show the form.

May I ask you what I'm doing wrong here?

The other question is should I use forms to show tabbed view in frontend?

Thank you.
