This widget to search posts in real time is a feature of Tag Groups (Premium plan). All filters displayed in the left panel under groups are WordPress tags. You can also hide them in an accordion or show by default a list of posts before a visitor selects any filter.
If you click on one of the recipes and then return to this page, the filter will remember your settings and position in the list.
There is also a horizontal layout where posts are displayed in masonry style.
Please find more information about the options here.
