If you would like to add custom items, or items that aren't currently in the Jetbuilt Database, you can create new items within the builder.
First, open your project to the Builder area.
Next, click +Add Items.
In the top right corner, click +Create New Item.
Then add the details of your custom product, and click Add and Close to finalize the product, or Add and Next to add more products.
This process will add the new product to your project, and save it to your Custom Products Database for future use.
