Once upon a time, this blog had a YouTube video by @MichaelGaigg describing how to hack a Sidebar Widget into a dropdown menu. Sadly, that video has been lost to the sands of time. Here is my attempt to recreate the method (and create a new variant) having seen the video once about six months ago.
- Add a Sidebar Widget. In the Style Tab, switch to px and set the width and height, as you'll get better results if the Sidebar stays a consistent size. You'll want the width to be about equal to the length of text. You want to set the height as low as you can. (This is a design decision. Do you need to display all your options at once or not? How much interactive space can you give up to this menu?) Then add about 20px to your number.
