This topic describes the behavior of the style comboboxCompleter.
When the style comboboxCompleter is active, the
ComboBox will have the following behavior:
- The combobox is editable, but only characters that match an item
in the list are allowed (if the list contains the item "aa" and the
item "ab", you can type "a", "aa", "ab", but nothing else. If you
paste text in the field, it will be truncated until the rule is fulfilled.
- The dropdown list will only display item which starts with the
same characters as the edit field. It is dynamically updated as you
type (if the list contains the item "aa" and the item "ab" and you
type "a", you will see both item displayed, but if you continue to
type another "a", you will only see "aa" in the list.
- The best match is automatically selected when leaving the field
(thus performing an "on change") as soon as you hit "TAB" key, even
if the input is not complete.
