If you want to have the product designer to stretch to the full-size when using it in a lightbox as in this example, you can easily achieve that with some CSS tweaks.
.fpd-modal-product-designer.fpd-modal-overlay>.fpd-modal-wrapper { padding: 60px 0 0 !important; } .fpd-modal-wrapper > .fpd-container { height: 100% !important; } .fpd-modal-product-designer .fpd-done { position: absolute; top: 0; left: 10px; } .fpd-modal-product-designer .fpd-modal-price{ top:0; left:100px; }
