CREATING SIMPLE JQUERY TREE VIEW WITHOUT PLUGIN

Here we are going to create a Simple Tree View with out using any plugins

Use the below code for tree view nodes:

<div class="tree">
<ul>
    <li><a>First Level</a>
    <ul>
        <li><a>Second Level</a></li>
        <li><a>Second Level</a></li>
        <li><a>Second Level</a></li>
    </ul>
    </li>
    <li><a>First Level</a>
    <ul>
        <li><a>Second Level</a>
    <ul>
        <li><a>Third Level</a></li>
        <li><a>Third Level</a></li>
        <li><a>Third Level</a>
    <ul>
        <li><a>Fourth Level</a></li>
        <li><a>Fourth Level</a></li>
        <li><a>Fourth Level</a>
    <ul>
        <li><a>Fifth Level</a></li>
        <li><a>Fifth Level</a></li>
        <li><a>Fifth Level</a></li>
    </ul>
    </li>
    </ul>
    </li>
    </ul>
    </li>
        <li><a>Second Level</a></li>
    </ul>
    </li>
        <li><a>First Level</a>
    <ul>
        <li><a>Second Level</a></li>
        <li><a>Second Level</a></li>
    </ul>
    </li>
</ul>
</div>

Use the below code for tree view node expand and collapse:

$( document ).ready( function( ) { $( '.tree li' ).each( function() { if( $( this ).children( 'ul' ).length > 0 ) { $( this ).addClass( 'parent' ); } }); $( '.tree li.parent > a' ).click( function( ) { $( this ).parent().toggleClass( 'active' ); $( this ).parent().children( 'ul' ).slideToggle( 'fast' ); }); $( '#all' ).click( function() { $( '.tree li' ).each( function() { $( this ).toggleClass( 'active' ); $( this ).children( 'ul' ).slideToggle( 'fast' ); }); }); });

Use the below code for Tree View design:

body, a {
    color: #3B4C56;
    font-family: sans-serif;
    font-size: 14px;
    text-decoration: none;
}
#logo
{
width: 505px;
margin: 0 auto;
text-align: center;
}
#pgtitle
{
margin: 0px 0px 20px;
font-size: 18pt;
}
a{
cursor:pointer;
}
.tree ul {
    list-style: none outside none;
}
.tree li a {
    line-height: 25px;
}
.tree > ul > li > a {
    color: #3B4C56;
    display: block;
    font-weight: normal;
    position: relative;
    text-decoration: none;
}
.tree li.parent > a {
    padding: 0 0 0 28px;
}
.tree li.parent > a:before {
    background-image: url("../images/plus_minus_icons.png");
    background-position: 25px center;
     content: "";
    display: block;
    height: 21px;
    left: 0;
    position: absolute;
    top: 2px;
    vertical-align: middle;
    width: 23px;
}
.tree ul li.active > a:before {
    background-position: 0 center;
}
.tree ul li ul {
    border-left: 1px solid #D9DADB;
    display: none;
    margin: 0 0 0 12px;
    overflow: hidden;
    padding: 0 0 0 25px;
}
.tree ul li ul li {
    position: relative;
}
.tree ul li ul li:before {
    border-bottom: 1px dashed #E2E2E3;
    content: "";
    left: -20px;
    position: absolute;
    top: 12px;
    width: 15px;
}
#wrapper {
    margin: 0 auto;
    width: 300px;
}

Now we can deploy the solution and we can get the simple tree view.

Thank you,
