Vertical header submenu hidden by main

Hi!

Thanks for a great theme! I´ve created a vertical header with OceanWP and are using a custom template from Theme Panel. I´ve created the template with Elementor and Jetmenu. The submenu are hidden by the main window of the site. I´ve tried to change the z-index but ge no result. Do you have any idea what I do wrong?
