Quick Start Example

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Ribbon
@using Syncfusion.Blazor.SplitButtons

<div style="width: 100%">
    <SfRibbon>
        <RibbonTabs>
            <RibbonTab HeaderText="Home">
                <RibbonGroups>
                    <RibbonGroup HeaderText="Clipboard" Orientation="Orientation.Row">
                        <RibbonCollections>
                            <RibbonCollection>
                                <RibbonItems>
                                    <RibbonItem Type="RibbonItemType.SplitButton">
                                        <RibbonSplitButtonSettings Content="Paste" IconCss="e-icons e-paste" Items="@pasteOptions">
                                        </RibbonSplitButtonSettings>
                                    </RibbonItem>
                                </RibbonItems>
                            </RibbonCollection>

                                <RibbonItems>
                                    <RibbonItem Type="RibbonItemType.Button">
                                        <RibbonButtonSettings Content="Cut" IconCss="e-icons e-cut" OnClick="@OnCut">
                                        </RibbonButtonSettings>
                                    </RibbonItem>
                                    <RibbonItem Type="RibbonItemType.Button">
                                        <RibbonButtonSettings Content="Copy" IconCss="e-icons e-copy" OnClick="@OnCopy">
                                        </RibbonButtonSettings>
                                    </RibbonItem>
                                </RibbonItems>
                            </RibbonCollection>

                </RibbonGroups>
            </RibbonTab>
        </RibbonTabs>
    </SfRibbon>
</div>

@code {
    private List<DropDownMenuItem> pasteOptions = new List<DropDownMenuItem>()
    {
        new DropDownMenuItem{ Text = "Keep Source Format" },
        new DropDownMenuItem{ Text = "Merge Format" },
        new DropDownMenuItem{ Text = "Keep Text Only" }
    };

    private void OnCut(MouseEventArgs args) { /* Handle cut action */ }
    private void OnCopy(MouseEventArgs args) { /* Handle copy action */ }
}

Common Patterns

1. Multi-Tab Ribbon

Organize related functionality into separate tabs with different commands:

<SfRibbon>
    <RibbonTabs>
        <RibbonTab HeaderText="Home"><!-- Home commands --></RibbonTab>
        <RibbonTab HeaderText="Insert"><!-- Insert commands --></RibbonTab>
        <RibbonTab HeaderText="Design"><!-- Design commands --></RibbonTab>
    </RibbonTabs>
</SfRibbon>

2. Grouped Commands

Group related items for better organization and UI layout:

<RibbonTab HeaderText="Home">
    <RibbonGroups>
        <RibbonGroup HeaderText="Clipboard"><!-- Copy/Paste items --></RibbonGroup>
        <RibbonGroup HeaderText="Font"><!-- Font items --></RibbonGroup>
        <RibbonGroup HeaderText="Paragraph"><!-- Alignment items --></RibbonGroup>
    </RibbonGroups>
</RibbonTab>

3. File Menu Integration

Include file operations menu:

<SfRibbon>
    <RibbonFileMenuSettings Visible="true" MenuItems="@fileMenuItems">
    </RibbonFileMenuSettings>
    <RibbonTabs><!-- tabs here --></RibbonTabs>
</SfRibbon>

4. Data-Bound ComboBox

Bind dropdown to data source:

<RibbonItem Type="RibbonItemType.ComboBox">
    <RibbonComboBoxSettings DataSource="@fontFamilies" 
                             FieldSettings="@fieldSettings"
                             AllowFiltering="true">
    </RibbonComboBoxSettings>
</RibbonItem>

5. Toggle Buttons

Create buttons with selected/unselected state:

<RibbonItem Type="RibbonItemType.GroupButton">
    <RibbonGroupButtonSettings Selection="GroupButtonSelection.Single" Items="@alignmentOptions">
    </RibbonGroupButtonSettings>
</RibbonItem>

Troubleshooting Tips

Ribbon not appearing:

• Check Disabled property not set to true

Styling issues:

• Confirm theme CSS is referenced in index.html
• Check for conflicting CSS rules
• Verify CssClass property syntax

Events not firing:

• Confirm event handler is bound with @
• Check parameter types match event args
• Verify component lifecycle (use Created event for initialization)

Next Steps

1. Start with Getting Started to install and set up the component
2. Learn Ribbon Structure to understand tab/group/item organization
3. Explore Item Types (Basic and Advanced) for different control options
4. Add File Menu for file operations
5. Implement Events for user interactions
6. Customize with Styling and Accessibility for production apps
