Horizontal flyout menu - hide options - html

Question

I need to create simple horizontal (left direction) flyout menu for button. I've prepared this DEMO.
.menu {
position: absolute;
right: 0;
height: 50px;
width: 50px;
color: white;
}
.menu li {
pointer-events: none;
position: relative;
display: inline-block;
vertical-align: middle;
list-style: none;
line-height: 100%;
transform: translateZ(0);
}
.menu a {
pointer-events: auto;
position: relative;
display: block;
min-width: 5em;
margin-bottom: .4em;
padding: .4em;
line-height: 100%;
font-size: 16px;
text-decoration: none;
color: white;
transition: background 0.3s;
}
.menu a:active, .menu a:focus {
background: #B44659;
}
.menu i {
display: block;
margin-bottom: .2em;
font-size: 2em;
}
.menu span {
font-size: .625em;
font-family: sans-serif;
text-transform: uppercase;
}
.menu li:hover ul {
transform: translateX(0);
background: #B44659;
}
.menu > li {
display: block;
}
.menu > li > a {
background: #7D294E;
}
.menu > li:hover {
z-index: 100;
}
.menu > li:hover a {
background: #B44659;
}
.menu > li a:hover {
background: #F56356;
}
.menu > li > a:after {
content: "";
position: absolute;
top: 0;
bottom: 0;
left: 100%;
width: 4px;
opacity: 0;
background: -moz-linear-gradient(left, rgba(0, 0, 0, 0.65) 0%, rgba(0, 0, 0, 0) 100%);
background: -webkit-gradient(linear, left top, right top, color-stop(0%, rgba(0, 0, 0, 0.65)), color-stop(100%, rgba(0, 0, 0, 0)));
background: -webkit-linear-gradient(left, rgba(0, 0, 0, 0.65) 0%, rgba(0, 0, 0, 0) 100%);
background: -o-linear-gradient(left, rgba(0, 0, 0, 0.65) 0%, rgba(0, 0, 0, 0) 100%);
background: -ms-linear-gradient(left, rgba(0, 0, 0, 0.65) 0%, rgba(0, 0, 0, 0) 100%);
background: linear-gradient(to right, rgba(0, 0, 0, 0.65) 0%, rgba(0, 0, 0, 0) 100%);
filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#a6000000', endColorstr='#00000000',GradientType=1 );
transition: opacity 0.5s;
}
.menu > li:hover a:after {
opacity: 1;
}
.menu > li ul {
position: absolute;
z-index: -1;
top: 0;
right: 100%;
height: 100%;
width: auto;
white-space: nowrap;
transform: translateX(100%);
background: #B44659;
transition: 0.5s transform;
}
<ul class="menu">
<li>
<a href="#">
<span>ITEM 1</span>

When you hover an item, the options slide from right to the left. The problem is to hide them - now they are just moved back to the right, but I would like to completely hide them. Is it possible to achieve this with pure CSS?

Answer 1

You can set overflow: hidden to your menu. Also you'll need to set a bigger width so when you slide the rest of the menu it won't overflow.
.visible-item{
width: 40px;
text-align: center;
}
.menu {
position: absolute;
right: 0;
height: 30px;
width: 50px;
color: white;
display: flex;
justify-content: flex-end;
overflow: hidden;
}
.menu:hover{
width: 400px;
}
.menu li {
pointer-events: none;
position: relative;
display: inline-block;
vertical-align: middle;
list-style: none;
line-height: 100%;
transform: translateZ(0);
}
.menu a {
pointer-events: auto;
position: relative;
display: block;
min-width: 5em;
margin-bottom: .4em;
padding: .4em;
line-height: 100%;
font-size: 16px;
text-decoration: none;
color: white;
transition: background 0.3s;
}
.menu a:active, .menu a:focus {
background: #B44659;
}
.menu i {
display: block;
margin-bottom: .2em;
font-size: 2em;
}
.menu span {
font-size: .625em;
font-family: sans-serif;
text-transform: uppercase;
}
.menu li:hover ul {
transform: translateX(0);
background: #B44659;
}
.menu > li {
display: block;

.menu > li > a {

.menu > li:hover a {
