- * Comboboxes have a read-only option for when content in the disabled state still needs to be shown. This allows for content to be copied, but not interacted with or changed. A combobox does not have a read-only option if no selection has been made. To enable this feature, add `isReadOnly` class to the Combobox. Then within the Textfield component add `isReadOnly` class and `readonly` attribute to the `<input>`.
