Provoking title of the article!
Why not directly giving a name to the article as
“Stop using the word drop-down. Instead choose a term that accurately describes the control you want.”
I thought you have some news about the techniques, but in fact it’s just a concern how people are refering to the current subject.
Well, leave that decision to people and let them describe their own way. For me a Drop Down term is clear. I click the select box and a drop down list spears. ComboBox let’s me search within the drop-down list. So, you won’t change my grammar and vocabulary on that and many others will agree with me.
It’s a programming language and not English literature.
