Checkbox in variable products

Hello @hrypa,

 i mean i have vegetables to choice from client, but i have only radio option

For something like this, it’s better to use a product add-on plugin. Most of them have a checkbox option.

Here’s an official solution by the Woo team: https://woocommerce.com/products/product-add-ons/

You can also try this free plugin (limited features): https://www.ads-software.com/plugins/woo-custom-product-addons/

Cheers!
