Hi,
- do vendors have a "shop page" listing all their products and is this page URL something like domain.com/vendorname/
If so, what is the selection process for the /vendorname/
Using a "vendor listing" menu, you can have something similar yes.
The vendor "alias" is used in the URL generation (like the product alias is used for the product's URL generation).
- Is it possible to have it that way also: vendorname.domain.com ?
It is possible but it requires a third party component or some custom development.
Joomla components like "JMS" (Joomla Multi Sites) allow you to create several websites using one Joomla instance and with the integration between JMS and HikaShop/HikaMarket ; you can create vendor stores per subdomain.
And while I'm at it, I took a look at your template packs and was wondering if you had any template to recommend that would match the "hikacar" pack (the clear background one).
We do not provide templates but we have a page which list templates made for HikaShop.
