I am trying to learn how to create custom ribbon in Excel just for my knowledge. I am trying to create ribbon similar like Home tab. But my vertical spacing is not like home tab. Picture can shown in details for better understanding about my issue. Also I am trying to find out how can I create bottom right corner icon. Please help me a idea, how to solve this problem.

<group id="ToolsGeneral" label="Sheet Tools">

         <box id="box" boxStyle="vertical">
            <dropDown  id="btnSheets"
                getItemCount="btnSheetCount"
                getItemLabel="btnSheets_getItemLabel"
                onAction="SheetsClick"
                sizeString="MMMMMMMMM" 
                label="Sheets" 
                getSelectedItemIndex="btnSheets_getSelectedItemIndex" />
           <box id="buttonGroup" boxStyle="horizontal">
               <button id="button1" imageMso="HappyFace" />
               <button id="button2" imageMso="HappyFace" />
               <button id="rxJKPSheetToolsbtnInsertToc"  
                            onAction="nsertTC"
                            imageMso="CustomTableOfContentsGallery" />
            </box>
        </box>
</group>
