    ];
}



protected function getOneinventoryoption()
{
    $getChooseOptions = [];
    $getChooseOptions[] = [
            'label' => 'Choose Options',
            'value' => '',
    ];
    $getChooseOptions[] = [
            'label' => 'Yes',
            'value' => '1',
    ];
    $getChooseOptions[] = [
            'label' => 'No',
            'value' => '2',
    ];
    return $getChooseOptions;
}

}

This is generated below layout

Now i need to call Related product section like Product grid over there.

How can i achieve this?
