Type: Feature Request
Accordion: Provide the option to collapse all items
Currently in RadAccordion one accordion item is always expanded.  I would need the option the accordion to be fully collapsed. In addition, when the header of an expanded item is clicked, it should be collapsed.

Would need this as well.
I would actually expand on this and have an enum, somethin like:
ExpandMode => ZeroOrOne, One, ZeroOrMore, OneOrMore
Which would mean:
ZeroOrOne = You can collapse all but can expand only one

One = There is always exactly one expanded

ZeroOrMore => You can collapse/expand any number of items at once

OneOrMore => There is always at least one item expanded, but you can also expand more at the same time.

Thank you Werner;


That is helpful.  I see the request is 'Approved' so I assume this will get fixed sooner rather than later with it being so simple.

Hi Joe, I'm currently using a workaround by handling the tap event on the label in the header template

           <radPrimitives:AccordionItem x:Name="AccordionItemTop10" IsExpanded="False">
                        <Label Text="{x:Static geaProps:Resources.RankingHighscores}" Style="{StaticResource ItemHeaderLabel}">
                                <TapGestureRecognizer Tapped="OnHeaderTapped" CommandParameter="{x:Reference Name=AccordionItemTop10}" />

private void OnHeaderTapped(object sender, EventArgs e)
            var parameter = (e as TappedEventArgs)?.Parameter;

            if (parameter is AccordionItem accordionItem)
                accordionItem.IsExpanded = !accordionItem.IsExpanded;

So I can collapse the currently open item so that all items are collapsed.

@Telerik: Think, it would be trivial to provide this behavior by an option out of the box ;-) One disadvantage of the workaround is that it does not react on taps onto the arrow.

This is exactly what we need also.
