Bug : editable dropdown not greyed out when disabled

I'm creating the following shipping form :

When the billing address is the same as the shipping address, the controls in the right column are disabled. But the dropdown does not have the same greyed-out look as the other controls. The dropdown is an editable dropdown, exactly as described here.

When I look at the generated html, the textbox in the dropdown has the same classes as the textbox below it.

Also : this is the code for the dropdown :

I have to set the Disabled property for the textbox in the ValueTemplate or it will be editable (even when the dropdown is disabled). I did not expect that. I would expect it to inherit the fact that it's disabled from the dropdown surrounding it.

You need to disable both components:


I did that (I edited my original post to reflect that).
The textbox indeed behaves disabled (I can't edit it), but it's not greyed out.

Check my screenshot.

I was using Radzen.Blazor v5.0.4, seems to indeed be solved in v5.1.5.

Thanks for the quick reply!
