Select only one variation

What about if you set the first variation of colours, you setup the attributes as normal. Then for the second variation, you would have a “none” attribute which is selected by default.

This gives the user the ability to give the option of ordering it or not. As well as allowing you to add pricing if needed.

Hi there!

By default, WooCommerce doesn’t offer a built-in way to have an optional variation (like a sample) that customers can select for a product without it being a required option. you’d typically need to use a plugin or custom code:

You can try to use a plugin like WooCommerce Product Add-Ons to add an optional checkbox or dropdown for the customer to choose whether they want to add a sample (second variation) to their order.This option lets customers decide if they want the sample without affecting the main product’s variations.

If you do not want to use the plugin, you can try use the option suggest by robin, alternatively, I can recommend?WooExperts?and?Codeable.io?as options for getting professional help. Alternatively, you can also ask your development questions in the??WooCommerce Community Slack?as custom code falls outside our usual?scope of support.
