The testimonial panel slides between those reviews that are specifically defined, or all reviews. The number of reviews shown, colours, timing, and other elements are all customised to your liking. Note the two blue squares below the slider - these are fully customisable button for pagination (you may also disable pagination entirely).
Note that while creation of reviews in Yabber is the preferred method of sending reviews to your website, you may simply create them in the 'Review' post category made available in WordPress. The latter method comes with some limitation.
A 'Black' and 'Gold' style applies to the star rating, with the latter typically used just about everywhere. Before the name of the individual that supplied the testimonial you'll see a small icon that shows where the review originated. The 'Occupation' field shown in the first pictured review is only available when that review is provided by Yabber.
Like any Elementor block, you simply drag and drop the Review slider into any position on your page. Once done, you define your various options, and the Review Slider will show.
All reviews are shown in a paginated archive in a style not entirely dissimilar to your blog, with the exception that the returned cards show only basic data. Each review links to a single testimonial page that optionally includes additional data as defined in Yabber (such as a user video review).
The modue is comprehensive. See our website for details.
