Hello, you may need to change the firstColums's min width and the secondColums' width attributes in your xml file while also considering the tab's percentage width.

I has the same prolem but, this site will cover all your needs in the Custom UI including the examples of the callback functions

Hello everyone by fumbling around I ended up finding my solution in fact it was necessary to use both firstcolumnminwidth and fistcolumnmaxwidth

`<customUI xmlns="http://schemas.microsoft.com/office/2009/07/customui"> <backstage> <tab id="tabb202401" firstColumnMinWidth="800" firstColumnMaxWidth="800" label="mes tutos sur youtube" > <firstColumn> <taskFormGroup id="grtask1"> <category id="truc"> <task id="ButtonTask1" label="Task" imageMso="HappyFace"> <group id="MyTestGroup1" label="Test Group 1"> <topItems> <labelControl id="Label1" label="Information about this button."/> <button id="Button1" style="large" label="Click me" imageMso="HappyFace" isDefinitive="true" onAction="TestMe"/> <labelControl id="Label2" label="Information about this button."/> <button id="Button2" label="Click me" imageMso="HappyFace" isDefinitive="true" onAction="TestMe2"/> </topItems> </group> </task>

			<task id="ButtonTask2" label="Task2" imageMso="HappyFace">		
                        <group id="MyTestGroup2" label="Test Group 2">		
                            <topItems>		
                                <labelControl id="Label3" label="Information about this button."/>		
                                <button id="Button3" style="large" label="Click me" imageMso="HappyFace" isDefinitive="true" onAction="TestMe"/>		
                             <labelControl id="Label4" label="Information about this button."/>		
                                <button id="Button4" label="Click me" imageMso="HappyFace" isDefinitive="true" onAction="TestMe2"/>		
                            </topItems>		
                        </group>		
                    </task>	

		 </category>		
            </taskFormGroup>
