I have a PPT add-in taskpane with multiple tabs. Some of them are hidden using a drop menu. I also have a custom Tab section in the Ribbon and I would like to add a button there for each tab, so when the user clicks it the corresponding tab should be selected.
Is this possible?
I'm sorry, but there's no way to pass parameters to an add-in command. You might try the following as a workaround. (I haven't tried this and I don't know if it will work.)
1. Set the action type for each button to ExecuteAction instead of ShowTaskpane.
2. Assign each button action to a different function.
3. Each function calls the `showAsTaskpane()` method and sets focus to the desired tab in the task pane. See [Show or hide the task pane of your Office Add-in](https://learn.microsoft.com/en-us/office/dev/add-ins/develop/show-hide-add-in).
