1 | Select To Autocomplete: Redesigned Country Selector
2 |
3 | An improved way to select a country in web forms.
4 |
5 | * Design improves upon a standard country dropdown list.
6 | * Accepts keyboard typing input.
7 | * Autocomplete from a list of synonyms.
8 | * Handles typos.
9 | * Prioritizes autocomplete results.
10 |
11 | The solution is a redesigned country selector that addresses the issues of drop-down country selectors. It handles typos, various spelling sequences, synonyms and prioritized options.
12 | The technically correct term for this would be something like an “auto-complete text field with loose partial matching, synonyms and weighted results.” That’s a bit long, so I’ve simply dubbed it the “Redesigned Country Selector”.
