Hi

What is the Ecommerce capability of WB16 like?

Are there official ecommerce features in the software like basket and checkout or do you have to use 3rd party plugins?

Are there any official or recommended ecommerce templates?

What is the Ecommerce capability of WB16 like?

First and foremost WB16 is a Web Design Tool not a e-commerce design tool.

Are there official ecommerce features in the software like basket and checkout

No as already mentioned the software is a Web Design Tool. (See links at end)

or do you have to use 3rd party plugins?

Yes (See links at end)

Are there any official or recommended ecommerce templates?

No
With all that said above you could install a 3rd party e-commerce script externally and then link to it from your navigation in your site made with the software.

If I can integrate an ecommerce solution into WB16 thats fine. Shopify is a good one so its good there is official support for that.

Most people will need some form of ecommerce on their site these days so this is pretty important now.

Note as the Shopify is a "Free" extension it is provided "asis" without support sorry. Any support or help is provided by Shopify code themselves.

I use ecwid for my clients for e-commerce. It works nicely with web builder. i also have a license for phpjabbers e-commerce but have not used it yet.
here is a sample site using web builder with the imbedded shop from ecwid

Be happy to help you determine if ecwid is a good fit.
