Collapsed groups in RibbonBar with Classic render mode do not expand

In lightweight the issue is not observed:

<telerik:RadRibbonBar runat="server" RenderMode="Classic">
    <Tabs>
        <telerik:RibbonBarTab Text="home">
            <%-- duplicate the group and items inside to replicate more easily --%>
            <telerik:RibbonBarGroup Text="Documents">
                <Items>
                    <telerik:RibbonBarButton Text="Item 1" />
                </Items>
            </telerik:RibbonBarGroup>
        </telerik:RibbonBarTab>
    </Tabs>
</telerik:RadRibbonBar>

Hi Daniel,

This behavior was originally reported over 5 years ago and has not received significant demand or follow-up from the community since then. Considering this, and the availability of a workaround for the discontinued in 2015 Classic render mode, we are unable to prioritize it over more impactful and widely requested improvements.

Our recommendation is to migrate your app to the supported Lightweight render mode.

Regards,

Thank you for reporting this Daniel, 

As a temporary workaround you can use the following style

<style>
    .RadRibbonBar .rrbButtonGroup.rrbDetachedGroup.rrbHidden,
    .RadRibbonBar .rrbButtonGroup.rrbDetachedGroup.rrbHiddenGroup {
        display: block !important
    }
</style>
