Scroll bar of Sub menus

Hi

I have added around 20 sub menus on our site https://www.xenexsoc.com/soc-overview under Soc-As-A-Service menu, the problem is I need to add a few more sub menus under the main menu Soc-As-A-Service but as we add it the menus get cutoff on the workstation mode/browser. I was expecting to get a scroll bar automatically as the number of menus increases. Is there a setting or functrion available to add the scroll bar for sub menus?

Thanks in Advance!

@xenexsoc Here's a code snippet to display a scrollbar on the first sub menu:

.header-nav-item--folder:nth-child(1) .header-nav-folder-content {
  max-height: 300px;
  overflow:auto;
}

You have the flexibility to modify the "max-height:300px" value in the code. This adjustment directly influences the height of the submenu. If the submenu accommodates more items, a scrollbar will be automatically be displayed.

Let me know how it goes. Thanks!
