Flatsome Support

In Order to support flatsome Theme some small custom CSS changes need to be applied if you want to use the nested categories layout:

.product.col {
	width: 25%;
	float: left;
	padding: 20px 15px 10px;
	min-height: 400px;
}
.WooCommerce .woocommerce-advanced-categories-list-element.woocommerce-advanced-categories-col-1 {
    max-width: 100%;
    -ms-flex-preferred-size: 100%;
    flex-basis: 100%;
}
