    1. COThanks for a great example ! But you should use onSelection() instead of onValueChange(). It's more appropriate for what we are trying to do here.

    2. CO@PhilippeCarriere I can't test this right now, but wouldn't the SuggestionEvent only be fired if you pick sonething from the list? With this solution I think you could type something that is not suggested. Like an email address not in the address book.

    3. COI assumed that we only wanted entries from the supplied list. But someone could indeed want to type in something not on that list.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
