Woocommerce Add products options on single product page (Custom theme builder)

Hello, I have a Woocommerce shop that has a custom product builder that when you select a color swatch-option, the layer changes on the image. The way the single product pages are built are that the custom product builder is displayed in a visual page editor (See attached image). The custom product builder only works with color swatches. I need to be able to add in the single product pages via the visual page editor some other products options such as Dropdowns and a text field. I don't know if there is a plugin or a way to generate some product options via a shortcode that can be added in the visual page editor. I'd need some advice on what can be done! The options doesn't affect the Total price. But the options needs to show up in the cart page when adding the item to cart. The options needs also to be displayed in the mail the customer receives when he checkout. Front-end look of the single-product: [login to view URL] (The dropdowns would appear after the square color swatches and before the price)
