Hi there!
Thanks for your query!
You need to use custom CSS for that. But customization support is prohibited here!
I can give you suggestions, if you use the following code in your custom CSS then it will look like this: https://prnt.sc/10xbvjp
So if you want this, here is the code:
.sp-megamenu-parent > li:not(:last-child):after{
display:none;
}
.sp-megamenu-parent > li > a, .sp-megamenu-parent > li > span {
display: flex;
justify-content: center;
width: 150px;
line-height: 20px;
}
Note: Path towards custom CSS:
Extensions>Templates>Styles>
Click on your current default template name then choose Template Options.
Then find custom CSS within the custom code.

Hope this helps!
