Question

1C-Bitrix

I would like to know how to call the data of one component in another component in Bitrix?
For example, there is a slider, this is the first component. There is a product catalog (description, photo, order button), this is the second component.
I want to make the products spin in the slider component.
How can I add all product data to the slider?

Answer 1

1. A component can return something
2. In the template of the first component, you can call the second (do not forget about caching)

Answer 2

Make a simple component template
