Hi Daniel,

Thank you for reporting this issue, and sorry that it was closed only because of the time that had passed.

We confirmed that collapsed groups in Classic render mode did not expand because of a CSS class mismatch. The problem is fixed and will be available in the upcoming this month Q3 2026 SP1 release.

After updating, clicking a collapsed group in the RibbonBar will open it as expected. Until then, the workaround from the comments remains valid.

Thank you for helping us improve the product.

Regards,

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.

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>
