Right now when a DropDownList has PopupHeight="Auto" the popup gets the height necesaary to display its items properly.

But when there are many items the popup also displays all items without a vertical scrollbar (maybe over the entire page and beyond), which is not good.

My suggestion would be to add a property for specifyig a "MaxPopupHeight" to limit the growth of the popup.

Also if "PopupHeight" is not specified it should take "Auto" as the default value instead of a static height in px, instead give the new "MaxPopupHeight" a limiting default value.

Posting this feature request as per your suggestion in my original forum post at: https://www.telerik.com/forums/data-source-using-scalar-list

I would like the DropDownList component to support lists of scalar values as data source. I.e:

<TelerikDropDownList Data="@MyList" bind-Value=@MyItem>

</TelerikDropDownList>
 
@functions {
    protected List<string> MyList = new List<string>() { "a", "b", "c" };
 
    protected string MyItem { get; set; } = "b";
}

The DropDownList would infer the scalar type from the Data property. The TextField items shown in the list (and the associated ValueField) would be the same: i.e. the value of each scalar in the list.
