Invisible element being hovered when it shouldn't - html

Question

I've coded a dropdown login form for my navbar, it works correctly but not entirely, it seems that it also drops down when I hover on the area where the form appears:
The mouse is just hovering on an area where the dropdown appears but it shoudn't do that, it should drop down when I hover ONLY on "ingresar", how can fix this? Also, I don't want my mouse to look like I can click on the form, it should look normal.
.login-box {
width: 350px;
height: 420px;
padding: 80px 40px;
box-sizing: border-box;
background: rgba(0, 0, 0, .8);
position: absolute;
right: 0px;
top: 100%;
opacity: 0;
}
.menu li:hover .login-box {
opacity: 1;
}
h2 {
margin: 0;
padding: 0 0 10px;
color: #efed40;
text-align: center;
}
.login-box p {
margin: 0;
padding: 0;
font-weight: bold;
color: white;
}
.login-box input {
width: 100%;
margin-bottom: 20px;
}
.login-box input[type="text"],
.login-box input[type="password"] {
border: none;
border-bottom: 1px solid #fff;
background: transparent;
outline: none;
height: 40px;
color: #fff;
font-size: 16px;
}
::placeholder {
color: rgba(255, 255, 255, .3);
font-family: sans-serif;
font-weight: bold;

.login-box input[type="submit"] {
border: none;
outline: none;
height: 40px;
color: #fff;
font-size: 16px;
background: #ff267e;
cursor: pointer;
border-radius: 20px;
}
.login-box input[type="submit"]:hover {

color: #262626;
}
.login-box a {

text-decoration: none;
}
<ul class="menu">

You need to set the dropdown to not visible, so no hover event can be applied in it
.login-box{
width: 350px;
height: 420px;
padding: 80px 40px;
box-sizing: border-box;
background: rgba(0, 0, 0, .8);
position: absolute;
right: 0px;
top: 100%;
opacity: 0;
/* === NEW ==== */
visibility: hidden;
}
.menu li:hover .login-box{
opacity: 1;
/* === NEW ==== */
visibility: visible;
}
visibility
