Rules for Intuitive UX
> Long dropdowns are ridiculous to navigate.But why, why, why? Why can't native dropdowns have an integrated search? Are we stuck in some sort of native UI limbo? Why aren't OS and browser developers doing anything about it. Why can't we have more advanced controls without div-soups and js galore?With just a little bit of intelligence we could have controls that adapt to the offered choices: for example if < N show radio buttons, else show a dropdown, if too many - show a search box with auto-complete.
