How to add multilevel attribute to a product in Magento2.0

[Vimal777]

I want to add products with multilevel attributes.

Do we have any functionality to achieve this through Magento 2.0 ?

Example:- 

Suppose we have a Product A under this there is an option to select or deselect subproduct B . If B  is selected then we need to ask the user whether he wants to go monthly subscription price nor Lifetime Price.

Hi @Vimal777,

I guess you should be able (OOTB) with Configurable products.

For example, you can create a product with multiple colors and, for each combination/variations, the sizes for those colors.

It will depend on the order of the attribute.

I will suggest you to explore configurable products adding your variations.
