Hello All,

I need to modify service portal header, when i added more menu item they will overlap with the login widget. I need to achieve this using the mega menu. But somehow i am not able to achieve this. I am attaching the screenshot, please have a look.

Please suggest me how i can achieve this using mega menu or is there any other way to handle this.

Thanks in Advance!
