The renderlet :AUTOCOMPLETE is very useful on search engines. It helps the user to find out the information he needs, by proposing him something when he's typing (on mouse press).

So, this control will be usually used into a renderlet:SEARCHFORM or even in collaboration with a simple renderlet:BUTTON.

You can see below a common example of autocomplete on google search engine :

This renderlet will basically generate an HTML like :

Code HTML generated by renderlet:AUTOCOMPLETE

The list of choices is generated dynamically, based on Ajax Requests, and it is triggered when the user types something into the input text. So, the time of response is optimal.

What is great with this control is that you can specify a /datasource to the list of choices. In fact, this option is required to be set. So, when the user types something, than a query is made on the database in order to update the list of proposals. You can also order and limit the list of choices from your datasource.

It is required to specify the list of /childs to be rendered on this control and how to be rendered with the aid of a /template file. You must specify at least one child for the rendering of this control. 

All these configurations makes from this renderlet a powerful control.

Set up the template file used to design the /childs area of this renderlet:AUTOCOMPLETE.

The /template and /childs sections are only used to design the list of choices, and not the linked input text. For, the input text, consider the use of /style or /class properties.

If all the items have the same design, then you can simply set up this:
  1. alternateRows="###ROW###"

  1. <childs>
  2. <renderlet:TEXT name="country" readonly="true" />
  3. <renderlet:TEXT name="iso_code" readonly="true" />
  4. </childs>
And the according template file:

  3. <!-- ###ROWS### begin-->
  4. <!-- ###ROW### begin-->
  5. {country} - {iso_code}
  6. <!-- ###ROW### end-->
  7. <!-- ###ROWS### end-->
  8. <div class="last">{autocomplete_search.numrows} choices</div>
