Disable Items in AdvComboBox


I would like disable some items in the AdvComboBox. These items should be visible, but in grey color or an other color. The item should not be selectable, if disabled. It schould be possible to enable/disable items by code like "ItemIndex.Enable".

I have not found any hint in the documentation.

Can you help here?

Thanks in advance.

With best regards,

Disabling at item level is unfortunately not a built-in feature.
