Hello,
I was wondering how can I display some products in a sub product option form based on the first one.
Example:
I sell phone cases.
The first dropdown menu would be the Brand of the phone (Xiaomi, Apple, Samsung, Huawei).
According to the one you will select, a second dropdown called “Model” will appear, displaying only the cases for the Xiaomi model.
Right now, the two dropdown menus are displayed and the second one (Model) doesn’t display the model according to the Brand.
I don’t know if I am clear, but if I am, how can I do this?
Thank you!
I had the same issues a while ago and ended up stumbling upon this app:
https://apps.shopify.com/advanced-product-options
and have used it ever since. Takes a little while to get used to its setup, but the support team are super helpful and answer any questions and will help you as much as they can with setup/customisation.

i hope this helps!
Thaanks for the advice.
Although, I would prefer to do it without an 3rd-arty app. Isn’t there any way to do it directly with shopify?
Personally, i spent a long time searching for a way to do it and couldnt find anything on it other than 3rd party apps that offer conditional logic and that app was the best of the bunch. Not sure how possible it is because all product pages will use the same template so I’m not sure how you could differentiate the conditional logic per product.
You may be able to commission a Shopify expert to create it for you, might be worth posting a job listing to see if its possible as they will have a lot more technical knowledge around liquid than me.
Thanks for your help and advices 
No problem happy to help!
