Which bold grid themes have a slideshow on the home page?

Thank you for contacting us.

The Primas theme uses a slider for the leaderboard images on the home page.  Please let us know if you have any other questions and we will do our best to answer them.

This depends. Are you trying to add a slider into the body of a page or post (for example, under the title) or are do you want a slider closer to the header of the page, more toward the top? If the former, there are plugins, like Metaslider, that let you achieve this more easily. If the latter, it will be slightly more difficult and would involve theme customization in the code itself.
