How to add similar products/items in one product

-- HikaShop version -- : Up to date

Hello,

I have something in mind that i have seen in many large selling websites (ebay,etsy etc) where you see one product that has multiple different products inside it,or just larger quantities with bigger price. Basically its a dropdown list where you can choose whatever variation you want on your product (as a customer) and this changes the price of the product.
I for example,want to sell a group of 10 very similar stones,but not identical ,so I want instead of creating 10 different products,create one where there is a dropdown list from which you can choose one of them.

Here an example of an ebay item with dropdown lists next to it. Changing a value in the list will change the final price of the item. I want to create something similar : www.ebay.com/itm/3W-5W-7W-9W-12W-E27-Ene...&hash=item35e7c5cc5d

Thank you for your time!

Thank you.

This is sort of what i am looking for. Basically because i sell different sizes of the same item ,I want when a larger size is selected the price will change. Also is it possible that (for example looking to buy water and a seller offers 3 different sizes 0.5,1 and 2 liters) once you click for example 2 liters the picture in the image slider automatically changes to show you the product you have chosen from the list,assuming that you have one picture for each different size. Is this possible ?
