Dropdown menu.
But ours open upward - 'popup', as in 'popup menu' has proved oddly confusing to some of our business oriented folk. So we tried throwing in 'vertical menu' and then.. this was a mistake.. 'vertical animating menu'.开发者_运维问答. so what would you call it?
Perhaps a "rise-up" or "spring-up" menu? If there's an animation attached to it, maybe a slide-up or a fade-in menu.
I understand the confusion about "popup" since many people think of popups as new browser windows that appear when you click a link.
"Context menus" are context-sensitive menus that appear at the site of a user interaction, such as a right-mouse click.
"Pull-down" menus are those that appear in menu bars.
