The name/text field comes from the LinkItem object where it is required.

An alternative to the LinkItemCollection is to create your own link list which can be done in a few different ways, the ideal solution would probably be using the Episerver.Url object. The Url object unfortunately lack a constructorless parameter so it is not usable in a IList property just yet, but it may be improved in 12.18. 

That implementation would in that case look like this

[Display(
    GroupName = SystemTabNames.Content,
    Order = 30)]
public virtual IList<Url> UrlList { get; set; }

Since we dont have that just yet, are you planning to link only internal pages and resources you'll probably find using a ContentReference list the easiest to implement, e.g. 

[Display(
    GroupName = SystemTabNames.Content,
    Order = 30)]
public virtual IList<ContentReference> ContentReferences { get; set; }

If you still want to use the Url property but create a custom propertylist something like this may suffice

[Display(
    GroupName = SystemTabNames.Content,
    Order = 30)]
[JsonProperty]
[JsonConverter(typeof(UrlConverter))]
[EditorDescriptor(EditorDescriptorType = typeof(CollectionEditorDescriptor<Link>))]
public virtual IList<Link> Urls { get; set; }

Where Link would be a property list looking something like this

public class Link
{
    [Display(Name = "Title", Description = "", GroupName = SystemTabNames.Content, Order = 1)]
    public virtual string NonRequiredTitle { get; set; }

    [Display(Name = "Link", Description = "", GroupName = SystemTabNames.Content, Order = 2)]
    public virtual Url LinkTo { get; set; }
}

[PropertyDefinitionTypePlugIn]
public class LinksProperty : PropertyList<Link> { }

I didn't really test the PropertyList<Link> solution with CMS 12 and it is heavily inspired by this solution https://world.optimizely.com/forum/developer-forum/CMS/Thread-Container/2019/6/url-property-disappear-when-adding-and-publishing/

Eric Herlitz Thank you for response.

I am agree with your alternate solution. But our requirement is to set any url that can be either internal or external. I am using LinkItemCollection becuase this property returns external url and internal page details both. But url property desn't return internal page detail. So I believe you alternate solution will not work for me

Here is LinkItemCollection property api response.
