I understand that this would open up the dropdown list but wouldn't it be empty since the default behavior is that when no text is entered, the suggestion list is empty?
The way I read Rob's question is:
1) How can we show a suggestion list -showing all suggestions - when no text has been entered YET.
2) And filter the suggestion list according the user entered text while typing
That way the control would be both a dropdown list with selectable items AND an autocomplete box showing the matching values from the list.
How should one setup the component to enable this behaviour?
