I am totally new to themeforest and the envato forum, so first of all I would like to apologize if I have put this message in the wrong place.
The reason for this message is that I want to build an eBay like site, with specific features, but I do not know which theme and templates I should use. The site will not include the number of products like eBay has, but only second-hand books for specific educational companies.
Marketify, by the @astoundify team is another excellent product. I can also vouch for the quality of their support.
From there, depending on the theme you choose, you may need to get a plugin to support the “hint” function. Although on CodeCanyon, this feature is known as a “search suggest” or “auto-suggest”.
As an example:
On the language front, some themes will already have this built in, it would be good to ask the author in the pre-purchase questions before you make your decision.
