hmm... If you are thinking that way you are wrong about Clickfunnels Clickfunnels is NOT Shopify
In Clickfunnels, we make thinks simpler for both customers and you (as the seller) take a single or even two types and then promote it... and instead of having a selector, just have a drop down same way they fill in their name and email, that drop down will have options for color...etc
But I personally find it awesome to just focus on a single product and single variant, because according to Trey Lewellen, adding an extra product/variant increases the complexity of your business process more than 12x times.
Why would you bother yourself giving too many options just focus on a single one and focus on having more upsells/downsells and Order bumps.
Also you can have a SALES page, the page has a number of options (buttons) when a user clicks one option they get taken to a different funnel...But that's simply an extra overhead, there are tons who got into the 2 comma club (making more than 1 million $ from e-commerce) without even having that kind of advanced or nice looking funnels... make it simpler + make it trustworthy... and that's it.
Hope that helps!
