How to make auto expand accordion?

Hi there,
I don’t use jQuery Vertical Accordion Menu because my DW MINION theme also have it. But it doesn’t seem to expand whenever I point my mouse to it.
I want these Accordions to expand whenever I point my mouse to, can you help me?

This is the code of Accordion in main.css:

.accordion {
  margin-bottom: 25px;
}
.accordion-group {
  margin-bottom: 10px;
}
.accordion-heading {
  border-bottom: 0;
}
.accordion-heading .accordion-toggle {
  display: block;
  padding: 10px 40px 10px 20px;
  font-size: 12px;
  line-height: 20px;
  text-transform: uppercase;
  position: relative;
  background: #7cc576;
  color: #ffffff;
  -webkit-border-radius: 2px;
  -moz-border-radius: 2px;
  border-radius: 2px;
}
.accordion-heading .accordion-toggle:hover {
  text-decoration: none;
}
.accordion-heading .accordion-toggle:after {
  content: "\f078";
  font-family: FontAwesome;
  position: absolute;
  right: 20px;
  font-size: 10px;
}
.accordion-heading .accordion-toggle.collapsed {
  background: #eee;
  color: #333333;
}
.accordion-heading .accordion-toggle.collapsed:after {
  content: "\f054";
}
.accordion-toggle {
  cursor: pointer;
}
.accordion-inner {
  padding: 15px 0 5px;
}
