As long as the form is a SQLFORM (including Crud and SQLFORM.grid), then
yes, that should be the default behavior simply by specifying a list:string
type field. SQLFORM automatically uses the SQLFORM.widgets.list widget for
list:string and list:integer fields, and that widget includes the
Javascript to implement the behavior. If you view the page source in your
browser, you should see the Javascript code inserted right after the UL.
