I tried to implement a search suggestion system with a datalist a few weeks ago only to find out that it was not stylable, there were zero events I could catch to find out an option was clicked/chosen, and there is no identifier possible for choices (so a display string is the value, no ID possible = impossible to localize or use for non-human-input values) Most shamefully lacking api on the web.
