Flex Slider - Arrows on Hover ?

Hello,

This is Definitely Possible. However, this something which is not available by default and a Small CSS Customization will be required to achieve this. Please add the following CSS Code:

.fslider.nav-on-hover .flex-prev,
.fslider.nav-on-hover .flex-next {
	opacity: 0;
	-webkit-transition: all .3s ease;
	-o-transition: all .3s ease;
	transition: all .3s ease;
}

.fslider.nav-on-hover:hover .flex-prev,
.fslider.nav-on-hover:hover .flex-next { opacity: 1; }

Then, you can simply add the .nav-on-hover Class to the .fslider Element.

This will definitely work fine. Let us know if we can help you with anything else or if you find any further issues.
