[Product-Developers] Archetypes livesearch widget

[Martin Aspeli-2]

Hi,

I need a "live search" widget for Archetypes that can fill a LinesField
with keys from a very large vocaulary, based on a search (for users, in
my case; possibly content later).

I know a few of these were kicking about, but I'm not sure what's most
up to date. Anyone have good experiences?

Cheers,
Martin

http://dev.plone.org/archetypes/browser/MoreFieldsAndWidgets/AutocompleteWidget
has been around for a few years and works fine.

It does not seem to use ajax?

I've been wanting to make my own selection widget for a while, but I
should probably help out with UberSelectionWidget or something similar.

I want to implement a "cache" in some hidden DOM element (probably an
ordered list since the browser will sort alphabetically). Then your
<select> queries the cache with normal javascript. If the cache misses
then the auto-complete returns false, but the cache goes off and makes
an ajax call to the server and retrieves a few more auto-complete
candidates. The next time the cache might hit, else the process continues.

No, but in a lot of situations ajax is not needed. Unless you have a
very large vocabulary this widget should work just fine.

If you need an ajax version it should be quite trivial to build one
using the jquery autocomplete plugin.

Cool. It seems to do exactly what I want. When I encounter the need to
use this type of widget again I'll try your suggestion.

No, but in a lot of situations ajax is not needed. Unless you have a
very large vocabulary this widget should work just fine.

using the jquery autocomplete plugin.

I need to select multiple users from a potentially large/slow LDAP repository. If the widget loads the vocabulary on access, then that doesn't work. In fact, the vocabulary won't be enumerated. Basically I want the formlib UberSelectionWidget, but for AT ;-)
