Custom Invalid Answer Layer for Graded Sequence Drop Down
I've successfully created custom invalid answer layers for graded questions in the true/false, multiple choice, and multiple response formats using the approach outlined in this tutorial: https://articulate.com/support/article/how-to-create-a-custom-invalid-answer-message.
However, I'd like to create a custom invalid answer layer for a graded sequence drop down question. My struggle is that I can't attach a conditional trigger to the drop down box options because they don't appear as individual objects on the slide. Has anyone successfully created a custom layer for this type of question?
I should mention that I do know how to customize the invalid answer message, but that's not what I'm looking to do. I want a customized invalid answer layer that matches the look and feel of the rest of my course, as well as the rest of the graded questions that I was able to figure this out for. Appreciate any ideas the community may have for me. Thanks!
