CMS: Setting Up the Selection Tags Input Element and Managing Tags
Give visitors a way to filter the items that appear on your live site or let them submit choices to your collection with the Selection Tags element. In your CMS (Content Management System) collection, you add the Tags field and manage the values associated with each item. If you need to apply changes to a tag value, the changes automatically apply to every item using the tag, so you don't have to manually edit them everywhere in your collection. In this article, learn more about: 
Using the Selection Tags input element to filter content on your live site Using the Selection Tags input element to collect content from site visitors Managing Tags in your CMS collectionUsing the Selection Tags input element to filter content on your live siteConnect the Selection Tags input element to the same dataset that connects to a repeater or gallery. Then set the element to filter content and choose which collection field's values you want to show as filter options in the Selection Tags element. When visitors click these filter options in the element, the repeater or gallery only displays items that have a matching field value. You can also apply advanced filtering conditions to choose an operator that controls how the filter is applied (e.g. Is any of, Equals any of, Includes any). Any filters or sorts you apply to the dataset also apply to the connected elements. This means you can add filters to the dataset to exclude items from appearing and add sorts to control their order. Wix EditorStudio Editor
