The Browse categories menu items must fit on the screen, in case menu items don’t fit, you need to somehow reorganize the menu. It is impossible to define the “scroll” there because in this case the drop-down submenus will be cut off by the “overflow”.
So you can add a limit in this from WoodMart > Heart Builder > Edit current header > configure categories settings and limit the categories: https://ibb.co/ynB5wb96
Sorry for the inconvenience. The option is available only for the Categories dropdown element, not for the simple menu item. You are currently using a simple menu with an aside menu, which is why this setting does not appear.
In this case, it is not possible to enable scrolling because the dropdown submenus would be cut off by the overflow. You will need to reorganize or reduce the menu items so they fit within the visible area.
