title: Related Product Grid
body: <p>In magento admin I am creating a lookbook module which will have a list of lookbooks and each lookbook can have images and related products. I have it working to the point where I can upload the images and able to save it but can't find a way to associate products to each lookbook. I'm thinking of to load a product grid (something like related product) and I can tick the checkbox for multiple products and get them saved for each lookbook. So the question is how can I load the product grid in custom module?</p>
