This is an other example form RichFaces:

http://livedemo.exadel.com/richfaces-demo/richfaces/comboBox.jsf?c=comboBox

This is a standard component that many GUI developers and users are familiar with. The autocomplete component is good but is not the same as a combo-box. Apart from the fact that the look and feel is different, a combo-box should be configurable to allow values not in the list.

JSF spec issue asking for a combobox. The linked blog mentions our lack of it.

http://java.net/jira/browse/JAVASERVERFACES_SPEC_PUBLIC-722

The new component has been added as of revision 33711.

1. Suggest that when clicking the down arrow to show the list, the entire list is shown, but the first matching value is highlighted, so anything typed will navigate to that row of the list if it matches. No match, start at top of list.

2. Component should not filter the list, but merely use typed chars to navigate and highlight a row in the list.
2a. When focussing on text field for first time, do not show list unless 'displayListOnFocus=true'.

Added missing attributes at revision 33924. Added label, indicator, and required styling demos at revision. 33936.

Closing issue.

• Fixed rounded corners in button to display a straight line to the left.
• Changed default filtering to 'none'.
• Change to display all rows by default.
• Set default height to 200px.
• Improved keyboard acceleration to find next match when not using filtering.
• Fixed issue with list reappearing after selecting a value.
• Added 'buttonOnlyList' attribute.
• Made component use ui-inputfield styling.

Changes:

1. Rename 'buttonOnlyList' attribute to "showListOnInput", default = true.
2. Modify the showListOnInput=true behavior to only show the list if the user types to edit the input field, not on focus or click.
