or maybe you mean in the blueprint?

I believe you’re asking how to bring back the tabs for Viewport, Construction and Event graph in the class viewer after closing them along the top.

If so, you can find the Viewport tab in Windows at the top.
And restore the Construction and Event Graph tabs by double clicking them on the left side “My Blueprint” panel.
