multiple variant

When i have for example 3 variants configured on my shopify.
When i display alls products on wordpress with the plugin, my integration is broken, because 3 variants overflow my theme.

Is existing a way to replace the add to cart, for product with variants, with just a link to the product page. And keep the add to cart for product without variants ?

I have a second problem, when i click on the select to choose a variant definition, my page is refresh and i can’t select the variant ?

Thanks a lot for your answer, i think that the 2 bugs remaining before finish my shop integration
