I would like to make this feature without having to add plugins.
In the woodmart functions we already have something very similar, but it is not intuitive.
In the image I show how my store is today, but I’m using a plugin.
With the plugin the site visitor selects only the size and the button changes the text to cart and the visitor can now add to cart.
Thank you for contacting us. We are working on this feature and it will be available in our 7.2 version. You can test how it works now in our 7.2-beta version which can be downloaded here https://xtemos.com/forums/topic/woodmart-7-2-beta/
