In custom CSS please add those lines:

.sp-megamenu-parent .sp-dropdown .sp-dropdown-items .sp-has-child > a::after {
  font-family: "Font Awesome 5 Free";
  content: "\f105";
  font-weight: 600;
}

AND If you don't need left blue arrow add also that

.sp-megamenu-parent .sp-dropdown li.sp-menu-item > a::before {display: none;}

after using both

Thank you so much Paul - I spent 2 hours yesterday trying to figure it out myself and now thanks to your super fast response it was fixed before the client ever saw it!

You get the gold star of the day!

Hi Paul,

I've got a similar behaviour on axioma.ro I tried the script you suggested for Syd but to no avail. Any other ideas?

@Marian, without url - not.

@Paul, what url, https://axioma.ro ?

Thanks

Somebody edited template.css file? It looks so... or you have old version of Helix.

Anyway, use below Custom CSS

body.ltr .sp-megamenu-parent > li.sp-has-child > a::after, 
body.ltr .sp-megamenu-parent > li.sp-has-child > span::after {content: "\f107"; }

Hi Paul, It worked very well. We have the latest version of Helix Ultimate, no recollection of somebody to mess up with the css files. But... Happy to see that it works.

Thank you

Marian

On my demo and private sites all works OK, that's why I was surprised by your mistake.
