I'm working on a product which has a bunch of selectors that can have anywhere between one, and several hundred possible selections with no way to be absolutely certain how many possible options there will be.
Right now I'm trying to determine which parts of the design are better served with a filtered radio button selection vs a combo-box based on expected ranges of options, but I'm running into a problem.
At what point (how large a list of possible selections) does the combo-box break, and is better served by the design on the right? (which is a modal dialog as opposed to the inline combo-box)
Relatedly, is there a better way of providing the the ability to select from a large list of potentially hundreds of results? (There can only be one selection, and it needs to be immediately visible/readable as text when the user is scanning up and down the page.
