CSS Tooltip Div and overflow hidden - tooltip

Question

I have a sidebar and inside it is a list of items and on some of them I will have a div/tooltip that will appear but I can't get the tooltip to show because of overflow-x:hidden
Is there a way to get .gps-tooltip in view where it is in my fiddle?

I am assuming the input field <input type="text" name="data_gpd" placeholder="That tooltip should be viewable"> isn't supposed to be in the list item of your jsfiddle.
But I made some slight changes to your css, removing the overflow is going to be the first thing you would have to do to make the tooltip appear. As far as I know there is no other way around an overflow hidden.
.menu_side .wrapper {
background-color: #F8F8F8;
border-right: 1px solid #D3D3D3;
display: block;
height: 100%;
width: 299px;
z-index: 5;
}
.menu_side .wrapper li {
-moz-box-sizing: border-box;
background-color: #FFFFFF;
border-bottom: 1px solid #D3D3D3;
padding: 10px;
position: relative;
transition: background 0.1s ease-in 0s;
}
.gps-tooltip {
background: none repeat scroll 0 0 #FFFFFF;
border: 1px solid #D3D3D3;
left: 100%;
padding: 10px;
position: absolute;
top: 0;
z-index: 15;
}
