Hi there,
At the moment, WoodMart’s Layout Builder can create and assign Single layouts for built-in types only (Single Product, Single Post, and the theme’s Projects), as well as WooCommerce pages like Shop, Cart, Checkout, and Thank You. Custom post types registered via CPT UI are not supported in the Layout Builder’s assignment conditions, so they won’t appear there.
There is no setting to enable this for third‑party CPTs, and updating the theme will not add this capability right now. If you’d like, we can pass this as a feature request to our team.
Kind Regards
