Sub-Menu typography

I wish this is added in GP core someday but for now, you can use some trusty CSS:

.main-navigation .main-nav ul ul li a {
	font-size: 13px;
	font-weight: normal;
    text-transform: capitalize;
}

@media (min-width: 1025px) {
    .main-navigation .main-nav ul ul {
	padding: 0.6em;
	}
}

In the example above, I have adjusted the sub-menu font size, weight, and transform. I’ve also added slight padding around the container on desktop sizes.

UPDATE: I guess our wishes have been answered! Since GeneratePress 3.1 and the addition of Dynamic Typography, you can now set the primary sub-menu typography right from the Customizer. Just go to Customizer -> Typography, and click the Add Typography button. Select Primary Sub-Menu Items from the Target Element dropdown and set your settings accordingly.
