angular tree control not highlighting the whole cell - angularjs

Question

I tried to implement angular tree control from http://wix.github.io/angular-tree-control, however, i cannot highlight the whole cell, it's only highlighting the label. I tried to change the css that the treecontrol comes with but still i can't make it highlight the whole cell.
the current and expected result is here:
treecontrol {
font-family: Verdana, Helvetica, Arial, sans-serif;
font-size:13px;
color: #555;
text-decoration: none;
}
treecontrol ul {
margin: 0;
padding: 0;
list-style: none;
border: none;
overflow: hidden;
}
treecontrol li {
position: relative;
padding: 0 0 0 20px;
line-height: 20px;
ul {
padding-left: 16px;
}
.tree-label {
cursor: pointer;
display: inline;
&:focus {
outline: none;
}
&:hover {
outline: none;
background-color: yellow;
}
}
.tree-selected {
background-color: yellow;
}
&.tree-expanded {
> div {
> .tree-icon-expand {
display: none;
}
> .tree-icon-collapse {
display: inline;
}
}
}
}
treecontrol li.tree-expanded i.tree-leaf-head, treecontrol li.tree-collapsed i.tree-leaf-head {display:none;}
treecontrol li.tree-expanded i.tree-branch-head, treecontrol li.tree-collapsed i.tree-branch-head {display:inline;}
treecontrol li.tree-leaf i.tree-branch-head {display:none;}
treecontrol li.tree-leaf i.tree-leaf-head {display:inline;}
treecontrol li i.tree-branch-head {
cursor: pointer;
}
treecontrol li.tree-expanded i.tree-branch-head {
padding: 1px 10px;
background: url("../images/node-opened-light.png") no-repeat;
}
treecontrol li.tree-collapsed i.tree-branch-head {
padding: 1px 10px;
background: url("../images/node-closed-light.png") no-repeat;
}
treecontrol li.tree-leaf i.tree-leaf-head {
padding: 1px 10px;
width: 16px; height: 16px;
background: none no-repeat;
}

You have an example in the same page that you linked
custom css classes
Your javascript would be
function CustomCss($scope) {
$scope.treedata=createSubTree(3, 4, "");
$scope.opts = {
injectClasses: {
"liSelected": "c-liSelected",
}
};
}
And your CSS
.c-liSelected {background-color: yellow}
