Problem with the themes sidebar. Its blocking a jQuery dropdown. I have a sliding panel but the panel don’t slide on pages that has sidebar.

Sidebar CSS:

#sidebar {
  list-style: none;
  margin: 0;
  padding: 0;
  width: 220px;
}
#sidebar.left {
  float: left;
}
#sidebar.right {
  float: right;
}
#sidebar > li {
  background-position: center top;
  background-repeat: no-repeat;
  margin-bottom: 15px;
  padding: 17px 0 0 0;
}
#sidebar > li:first-child {
  background: none;
  padding-top: 0;
}
#sidebar.left > li {
  padding-right: 20px;
}
#sidebar.right > li {
  padding-left: 20px;
}
#sidebar .title {
  font: bold italic 25px/25px Georgia, serif;
  text-transform: lowercase;
  margin-bottom: 15px;
}
