Hello,
According to the fact those blocks were created with an additional plugin we could propose the next solutions only with custom CSS
make max-height of filters
1/
.shop-filters .wcf-popover-body .inside-filter {
max-height: 200px;
overflow: auto;
}
2/ make the wishlist invisible until the customer will interact with the product (make hover on the product)
.add-to-wishlist-before_image:not(:hover) .yith-wcwl-add-to-wishlist {
opacity: 0;
visibility: hidden;
}
.add-to-wishlist-before_image .yith-wcwl-add-to-wishlist {
transition: all .3s linear;
}
Regards
