    The Tags property editor allows you to add multiple tags to a node.

    Data Type Definition Example

    Tag group

    The Tag group setting provides a way to categorize your tags in groups. So for each category you will create a new instance of the Tags property editor and setup the unique category name for each instance. Whenever a tag is added to an instance of the tags property editor it's added to the tag group, which means it will appear in the Typeahead list when you start to add another tag. Only tags that belong to the specified group will be listed. If you have a "Frontend" group and a "Backend" group the tags from the "Frontend" group will only be listed if you're adding a tag to the Tags property editor configured with the "Frontend" group name and vice versa.

    Storage type

    Data can be saved in either CSV format or in JSON format. By default data is saved in JSON format. The difference between using CSV and JSON is that with JSON you can save a tag, which includes comma separated values.

    Since the release of Umbraco 7.6 there are built-in property value converters, which means you don't need to worry about writing them yourself or parse the JSON output when choosing "JSON" in the storage type field. Therefore the last code example on this page will work out of the box without further ado.

    MVC View Example - displays a list of tags

    Typed using models builder

            @foreach(var tag in Model.Content.Tags){

    using GetPropertyValue

    @if(Model.Content.GetPropertyValue<IEnumerable<string>>("tags") !=null){
            @foreach(var tag in Model.Content.GetPropertyValue<IEnumerable<string>>("tags")){

    Setting Tags Programatically

    You can use the ContentService to create and update Umbraco content from c# code, when setting tags there is an extension method (SetTags) on IContentBase that helps you set the value for a Tags properties. Remember to add the using statement for Umbraco.Core.Models to take advantage of it.

    using System.Web.Mvc;
    using Umbraco.Core.Models;
    using Umbraco.Web.Mvc;
    namespace Our.Documentation.Examples.Controllers
        public class TestController : SurfaceController
            // GET: Test
            public ActionResult Index()
                //get content item to update
                IContent content = Services.ContentService.GetById(1234);
                // list of tags
                string[] newTagsToSet = new string[] { "Umbraco", "Example","Setting Tags", "Helper" };
                //tag storage type, this is an enum and can be either Csv or Json
                TagCacheStorageType storageType = TagCacheStorageType.Csv;
                //whether to add/merge with any existing tags or replace completely existing tags with this new set of tags
                bool replaceTags = true;
                //optional tagGroup
                string tagGroup = "default";
                // set the tags
                content.SetTags(storageType, "aliasOfTagProperty", newTagsToSet, replaceTags, tagGroup);
                return View();
