Displaying all the items

For Orbeon Forms 3.9  [SINCE 2010-06-11]

The autocomplete control shows suggestions as users start typing in the field, based on what they have already typed. What if users don't know what to start typing? This is where the show-full-itemset-dropdown="true" attribute comes into play. Add it to your <fr:autocomplete>, and you'll see a button added next to the text field:

When users click on it, they will see the full list of items from which they can make a selection.

Since for show-full-itemset-dropdown="true" to work, the component needs to have access to the full itemset, not just the partially loaded item load based on what users typed so far. So you can only use show-full-itemset-dropdown="true" when you are in static itemset mode.
