Re: Drop Down List question...

Here is an example of the method in the page backing bean

public Option[] getOptions() {

List<Option> options = new ArrayList<Option>();

personDataProvider.cursorFirst();

Option firstOption = new Option(personDataProvider.getValue("PERSON.PERSONID"), (String) personDataProvider.getValue("PERSON.NAME"));

options.add(firstOption);

Option filler = new Option(99999, "----------");

options.add(filler);

while (personDataProvider.cursorNext()) {

Option option = new Option(personDataProvider.getValue("PERSON.PERSONID"), (String) personDataProvider.getValue("PERSON.NAME"));

options.add(option);

}

return options.toArray(new Option[options.size()]);

}

Here is the component binding

<webuijsf:dropDown id="dropDown2" items="#{Page1.options}" label="Option List With Filler" style="left: 72px; top: 72px; position: absolute"/>

Here is an example of how to do it including source code on my blog.

Hi, :D

I got a question about the Drop Down List component for the visual web.

I got a binding to a database for the component items, there are four of them the component is something like this:

[1, "Value one"]

[2, "Value two"]

[3, "Value three"]

[4, "Value four"]

But I need to do this plus something more:

[1, ""]

[___________]

[2, "Value one"]

[2, "Value two"]

[2, "Value three"]

[2, "Value four"]

I mean, I want a first value with no label, a line separator and the database values.

Is this posible???

Can anybody helpme with this please.

Thanks!!
