Hello,
Product page and products are the functionality of Woocommerce. Our theme does not influence this
Please find here all the option you can get creating a variable product – one product – a lot of variation https://docs.woocommerce.com/document/variable-product/
And a Grouped product – group of simple products which can be sold both in a group or independently: https://woocommerce.com/videos/woocommerce-grouped-product-overview/
Best Regards
