I need to create a tree structure using html and css.
Structure should be like this.
Current css and html for this:
ul{
list-style: none;
}
ul li{
background: #F4F4F4;
}
li.active{
background: #B7E9FB!important;
}
<ul>
<li class="drag-folder">
<a href="javascript:void(0);">
<span>TEST1.1</span>
</a>
<div class="nested-list">
<ul style="display:block">
<li class="drag-folder">
<a href="javascript:void(0);">
<span>TEST1.2</span>
</a>
<div class="nested-list">
<ul style="display:block">
<li class="drag-folder">
<a href="javascript:void(0);">
<span>TEST1.3</span>
</a>
<div class="nested-list">
<ul style="display:block">
<li class="drag-folder">
<a href="javascript:void(0);">
<span>TEST1.4</span>
</a>
<div class="nested-list">
<ul style="display:block">
<li class="drag-folder active">
<a href="javascript:void(0);">
<span>TEST1.5</span>
</a>
<div class="nested-list">
<ul style="display:block">
<li class="drag-folder">
<a href="javascript:void(0);">
<span>TEST1.6</span>
</a>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
</div>
</li>
</ul>
This structure can have n number of nodes.
Problem:
nested elements width is less than root element width because of left padding (applied padding to display hierarchy), so on hover background color changes only for that particular width.
I want to make width of all li element to 100% of root element so on active background color will change for 100% width of display area, but need to maintain hierarchy.
I would like to have css solution for it.
Thanks in advance.

You can change your CSS like this:
ul{
list-style: none;
}
ul li{
background: #F4F4F4;
}
ul li a{
display:block;
}
li.active a{
background: #B7E9FB!important;
}
