How do I keep my horizontal secondary navigation bar active? It disappears too quickly

Hello squarespace community!

How do I keep my secondary navigation bar active ? Currently it fades/disappears before I can click on any sub categories.
I would like it to stay active so I can hover across the secondary options and click through.

Any support appreciated. Thank you ! Luna

This is my current CSS
//* Header Hortizontal sub menu *//
.header-nav .header-nav-item--folder .header-nav-folder-content{
 top:3.5vw;
 width: 100%!important;
 position:fixed!important;
 background: #E3D5B5!important;
 border-top: 1px solid #000;
 border-bottom: 1px solid #000;
  z-index: -1;
}
.header-nav-folder-content{
 display: flex;
 justify-content: center;
}
.header-nav-folder-item {
 margin-left: 1.5rem;
 margin-right: 1.5rem;
}

/*Nav Item Animated Line when hover*/
nav a:hover {
    background-size: 100% 2px 
      overflow: visible !important;
background-repeat: no-repeat !important;
}

nav a {
  padding-bottom: 6px;
  overflow: visible !important;
background-repeat: no-repeat !important;
    background-image: linear-gradient(to right,currentColor 100%,currentColor 0) !important;
    background-size: 0% 2px !important;
    background-position: 0% 100% !important;
    white-space: initial;
transition: all ease-in-out 500ms !important;
-ms-transition: all ease-in-out 500ms !important;
-moz-transition: all ease-in-out 500ms !important;
-webkit-transition: all ease-in-out 500ms !important;
}
/*Transparent dropdown background */
.header-nav-folder-content {
   background: transparent !important;
  a {
   background: none !important;
    
}
}
/*Nav Folder Dropdown Fade In*/
.header-nav-folder-content {
  transition: all 0.5s ease-in-out !important;
}
.header-nav-folder-content:hover {
  transition: all 0.5s ease-in-out !important;
}

/* Hover underline */
.header-nav-item.header-nav-item--folder:hover>a {
    background-size: 100% 2px !important;
}
