    <p>I have this little "application", and I want when someone type in a AutoComplete textbox for example "New" it automatically displays "New York" as a option and that (AutoComplete function) works fine. But I want when user type in full location (or AutoComplete do it for him) - that text (location) input is forwarded to a database search which then searches through database and "collects" all rows with user-typed location. For example if user typed in "New York", database search would find all rows with "New York" in it. When it finds one/more row(s) it would display them below.

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.

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