If you have just the WooCommerce core plugin, then you can’t do exactly that. I don’t know of a plugin that would do it. It should be possible with some custom code if you have a developer.

I would do it by having “Not available” as an attribute for “splitting”. When you make your variations, either make them individually or “make from all attributes” then delete the combinations that you don’t offer.

The variations threshold is usually 30. If you have less than that, then unavailable combinations of attributes will not be selectable.

If necessary, you can increase the variations threshold with this snippet:

Hello,

If you are up for using another plugin, you might want to check out the following plugins. They can show/hide different fields based on information they fill out

This isn’t necessary. Just have “None” as an option for your colour attribute. Ensure all your wooden and canvas variations are only available with the “None” colour. Ensure your number of variations is less than the variations threshold of 30, or increase the threshold until it is. Ordinary WooCommerce will do the rest.

Hi @niranjan9431

Glad to know @lorro’s suggestion helped solved the problem. Cheers!
