How can we get this design on iOS, where it seems we have a larger navigation bar or somewhat of a sticky bar inside the opened groupChannel(at the top always below navbar)

here is pic with example of what im trying to recreate for the navigation bar(notice the `32 participants ` also in the navbar

If I can’t expand the navbar to make it longer, is there a way to add a sticky bar right under the navbar?

I tried `preferLargeTitles` to increase the navbar size but this didn’t work either

Hello @NerdyYawdie,

I just checked your issue.  
unfortunately, UIKIT has not yet officially provided largeTitle funtion of navigationBar.  
but, you can customize it if necessary.  
please refer to the snippet below.

```auto
class CustomGroupChannelViewController: SBUGroupChannelViewController {
    override func setupViews() {
        super.setupViews()
        
        self.navigationController?.navigationBar.prefersLargeTitles = true
    }

    open override func viewWillDisappear(_ animated: Bool) {
        super.viewWillDisappear(animated)
        
        self.navigationController?.navigationBar.prefersLargeTitles = false
    }
    
    override func baseChannelModule(_ headerComponent: SBUBaseChannelModule.Header, didUpdateTitleView titleView: UIView?) {
        // After the `titleView` is set in the header component of the module,
        // if you required for control in the `viewController`, you can handle `titleView` in here .
    }
}

// Register your `CustomGroupChannelViewController` to `SBUViewControllerSet`
SBUViewControllerSet.GroupChannelViewController = CustomGroupChannelViewController.self

```

```auto
class CustomGroupChannelModuleHeader: SBUGroupChannelModule.Header {
    override func setupViews() {
        super.setupViews()
        
        self.titleView = {YOUR_CUSTOMIZED_TITLEVIEW}
    }
}

// Register your `CustomGroupChannelModuleHeader` to `SBUModuleSet`
SBUModuleSet.groupChannelModule.headerComponent = CustomGroupChannelModuleHeader()

```
