If you are using Sitecore 7 then you can use coded field datasources. This will allow you to use any custom logic you like to specify the items which should appear in your lists.
Create a class that implements IDataSource
and the ListQuery()
method that returns a list of Items as the source of your field. Then set the source of your field to your method with the code:
prefix, e.g. code:MyProject.Custom.FieldDataSource,MyProject.Custom
using System;
using Sitecore.Buckets.FieldTypes;
using Sitecore.Data.Items;
namespace MyProject.Custom
{
public class FieldDataSource : IDataSource
{
public Item[] ListQuery(Item item)
{
var root = item.Database.GetItem("/sitecore/content/my-item");
// some other logic to filter your item set
return root.Children.ToArray();
}
}
}
