CoreUI for React v5.11.0 - Search Button & Sidebar Nav Tree

Sunday, May 17, 2026

We are excited to announce the release of CoreUI for React v5.11.0. This update introduces the new Search Button component, a tree variant for Sidebar Nav, important bug fixes for CDropdown, CTooltip, and CPopover, and refreshed dependencies across the stack.

Speed up your responsive apps and websites with fully-featured, ready-to-use open-source admin panel templates—free to use and built for efficiency.

How to Update

To update your project to CoreUI for React v5.11.0, follow these steps:

Open your project’s package.json.
Locate the @coreui/react entry under dependencies and update the version number to 5.11.0.
Find the @coreui/coreui entry under dependencies and update the version number to ^5.7.0.
Save your changes to the package.json file.
In your project’s root directory, run the update command appropriate for your package manager:
- For npm users, execute npm install.
- For yarn users, execute yarn install.
- For pnpm users, execute pnpm install.

What’s New

Features

CSearchButton: New component providing a keyboard-shortcut-aware search trigger button. Displays the platform-appropriate shortcut hint (⌘K on macOS, Ctrl+K on Windows/Linux) and offers a clean, accessible entry point for search interfaces.
CSidebarNav - Tree Variant: Added a tree variant to the sidebar navigation, enabling hierarchical tree-style navigation structures. Includes narrow visibility helpers for better responsive behavior in collapsed sidebar states.

Bug Fixes

CDropdown: Corrected the default variant prop value from 'btn-group' to 'dropdown', ensuring the component uses proper default styling and behavior.
CTooltip & CPopover: Fixed an issue where the onHide callback was incorrectly triggered on initial mount when the component was in a hidden state. The effect now checks for actual visibility before calling handleHide.
