# Example: syndicate children of multiple items

You can implement a custom RSS feed based on the following example that syndicates the children of all of the items selected in the field named `Sources` in the feed definition item.

1. In the Visual Studio Web application project, compile a class based on the following example:

    ```csharp
    namespace Sitecore.Sharedsource.Syndication
    {
        public class SelectionFeed : Sitecore.Syndication.PublicFeed
        {
            public override System.Collections.Generic.IEnumerable<Sitecore.Data.Items.Item> GetSourceItem()
            {
                Sitecore.Data.Fields.MultilistField entries = this.FeedItem.Fields["Sources"];

                if (entries == null || entries.Count < 1)
                {
                    return new Sitecore.Data.Items.Item[0];
                }

                Sitecore.Collections.ItemList list = new Sitecore.Collections.ItemList();

                foreach (Sitecore.Data.Items.Item parent in entries.GetItems())
                {
                    foreach (Sitecore.Data.Items.Item child in parent.Children)
                    {
                        if (Sitecore.Syndication.FeedUtil.IsConfiguredForFeed(child))
                        {
                            list.Add(child);
                        }
                    }

                }

                if (list.Count < 1) {
                    return new Sitecore.Data.Items.Item[0];
                }

                list.Sort(new Sitecore.Data.Comparers.UpdatedComparer());

                return list.ToArray();
            }
        }
    }
    ```

2. In the **Template Manager** or the **Content Editor**, in the *System/Feeds/RSS* Feed data template, in the **Extensibility** section, add a **Treelist** field named **Sources**, and set the **Source** property of this field to the */sitecore/content* item.
3. In the **Content Editor**, in the feed definition item, in the **Extensibility** section, in the **Type** field, enter the signature of the class: `Sitecore.Sharedsource.Syndication.MultiParentFeed, Assembly`
4. In the **Content Editor**, in the feed definition item, in the **Extensibility** section, in the **Sources** field, select items with children to syndicate.
