Programmatically hide dashboard Tabs

It is OneStream, so anything is possible :)

I agree with JackLacava​ about look and performance of tabs. 

You could also probably achieve what you want by simply using an embedded dashboard approach.  For example if each tabbed dashboard layout was represented by a different dashboard, you could just show the one you want based on your condition(s) e.g. pass that value to the embedded dashboard via a parameter or onload event. 

Since your tabs are basically embedded dashboards, they could be reused between your different dashboard layouts and you would avoid handling all the micro actions to show/hide different elements within a single dashboard

This no/low code approach has a bit less finesse, but I believe would achieve the same effect :D

Hope this helps
