I use combo boxes often, but am confused as to why some work well and others don't.
Sometimes, I start typing the text I want, and the list automatically finds the relevant entry; other times, the list is there, but I have to scroll down to find what I want.
For instance, on one menu, I type j and it moves immediately to the first J- jamc; as I continue typing, it moves to the relevant entry - jond. I can see this happening, I don't need to pull down the list. This means I don't have to know the exact spelling, or do a long scroll dowm
In other places, I have to know exactly what I need to type, or scroll down till I find it.
Does that make sense?
