I've come across an issue that I'd like some input on before making an issue on GitHub. When hiding a tab using the

SendingContentNotification

and that tab has a property using the

Umbraco.DropDown.Flexible

editor then the selected value inside that dropdown is lost when the node is saved by someone who doesn't see that tab. This behaviour is different from some other editors like the

Umbraco.RadioButtonList

or the

Umbraco.TextBox

. What causes this property editor to behave differently and is this intended? And is this something that is worth making an issue for in GitHub?

How are you removing the tab?

cs
    public void Handle(SendingContentNotification notification)
    {
        if (IsAdmin())
        {
            return;
        }

        var content = notification.Content;
        var variants = content.Variants;

        foreach (var variant in variants)
        {

            variant.Tabs = variant.Tabs.Where(x => x.Alias != "settings");
        }
    }

This is a simplified version I've build to see if this is also an issue in Umbraco v12 but it's the same principle.

Instead just change the alias to "" it wont render but the validation will trigger but this is can also be removed

Thanks! It's actually not the Alias property but Label property that needs to be set to an empty string but that works. Thank you again for the help!

Finally able to check my code 😄 So I am setting Type to empty

For Umbraco V8 the

tab.Type

is an integer. Setting it to -1 also hides the tab in that version.
