Trees in Twitter Bootstrap

JavascriptJqueryTwitter BootstrapCssJquery Ui

Javascript Problem Overview

I have been trying to work on creating a tree (like a directory tree) that uses as much CSS and as little JS as possible (only for states, etc), and I want to know if there are some good existing tree plugins for bootstrap or jquery-ui bootstrap.

For reference or for people confused about this question, I am looking for something like dynatree for bootstrap.

Solution 1 - Javascript

Building on Vitaliy's CSS and Mehmet's jQuery, I changed the a tags to span tags and incorporated some Glyphicons and badging into my take on a Bootstrap tree widget.

Example: my take on a Bootstrap tree widget

For extra credit, I've created a Github iconGitHub project to host the jQuery and LESS code that goes into adding this tree component to Bootstrap. Please see the project documentation at http://jhfrench.github.io/bootstrap-tree/docs/example.html.

Alternately, here is the LESS source to generate that CSS (the JS can be picked up from the jsFiddle):

@import "../../../external/bootstrap/less/bootstrap.less"; /* substitute your path to the bootstrap.less file */
@import "../../../external/bootstrap/less/responsive.less"; /* optional; substitute your path to the responsive.less file */

/* collapsable tree */
.tree {
	.border-radius(@baseBorderRadius);
	.box-shadow(inset 0 1px 1px rgba(0,0,0,.05));
	background-color: lighten(@grayLighter, 5%);
	border: 1px solid @grayLight;
	margin-bottom: 10px;
	max-height: 300px;
	min-height: 20px;
	overflow-y: auto;
	padding: 19px;
	a {
		display: block;
		overflow: hidden;
		text-overflow: ellipsis;
		width: 90%;
	}
	li {
		list-style-type: none;
		margin: 0px 0;
		padding: 4px 0px 0px 2px;
		position: relative;
		&::before, &::after {
			content: '';
			left: -20px;
			position: absolute;
			right: auto;
		}
		&::before {
			border-left: 1px solid @grayLight;
			bottom: 50px;
			height: 100%;
			top: 0;
			width: 1px;
		}
		&::after {
			border-top: 1px solid @grayLight;
			height: 20px;
			top: 13px;
			width: 23px;
		}
		span {
			-moz-border-radius: 5px;
			-webkit-border-radius: 5px;
			border: 1px solid @grayLight;
			border-radius: 5px;
			display: inline-block;
			line-height: 14px;
			padding: 2px 4px;
			text-decoration: none;
		}
		&.parent_li > span {
			cursor: pointer;
			/*Time for some hover effects*/
			&:hover, &:hover+ul li span {
				background: @grayLighter;
				border: 1px solid @gray;
				color: #000;
			}
		}
		/*Remove connectors after last child*/
		&:last-child::before {
			height: 30px;
		}
	}
	/*Remove connectors before root*/
	> ul > li::before, > ul > li::after {
		border: 0;
	}
}

Solution 3 - Javascript

If someone wants vertical version of the treeview from Harsh's answer, you can save some time:

http://jsfiddle.net/Fh47n/

.tree li {
    margin: 0px 0;
	
	list-style-type: none;
    position: relative;
	padding: 20px 5px 0px 5px;
}

.tree li::before{
    content: '';
	position: absolute; 
    top: 0;
	width: 1px; 
    height: 100%;
	right: auto; 
    left: -20px;
	border-left: 1px solid #ccc;
    bottom: 50px;
}
.tree li::after{
    content: '';
	position: absolute; 
    top: 30px; 
	width: 25px; 
    height: 20px;
	right: auto; 
    left: -20px;
	border-top: 1px solid #ccc;
}
.tree li a{
    display: inline-block;
	border: 1px solid #ccc;
	padding: 5px 10px;
	text-decoration: none;
	color: #666;
	font-family: arial, verdana, tahoma;
	font-size: 11px;
    border-radius: 5px;
	-webkit-border-radius: 5px;
	-moz-border-radius: 5px;
}

/*Remove connectors before root*/
.tree > ul > li::before, .tree > ul > li::after{
	border: 0;
}
/*Remove connectors after last child*/
.tree li:last-child::before{ 
      height: 30px;
}

/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
	background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after, 
.tree li a:hover+ul li::before, 
.tree li a:hover+ul::before, 
.tree li a:hover+ul ul::before{
	border-color:  #94a0b4;
}

Solution 4 - Javascript

For those still searching for a tree with CSS3, this is a fantastic piece of code I found on the net:

http://thecodeplayer.com/walkthrough/css3-family-tree

HTML

<div class="tree">
  <ul>
    <li>
      <a href="#">Parent</a>
      <ul>
        <li>
          <a href="#">Child</a>
          <ul>
            <li>
              <a href="#">Grand Child</a>
            </li>
          </ul>
        </li>
        <li>
          <a href="#">Child</a>
          <ul>
            <li><a href="#">Grand Child</a></li>
            <li>
              <a href="#">Grand Child</a>
              <ul>
                <li>
                  <a href="#">Great Grand Child</a>
                </li>
                <li>
                  <a href="#">Great Grand Child</a>
                </li>
                <li>
                  <a href="#">Great Grand Child</a>
                </li>
              </ul>
            </li>
            <li><a href="#">Grand Child</a></li>
          </ul>
        </li>
      </ul>
    </li>
  </ul>
</div>

CSS

* {margin: 0; padding: 0;}

.tree ul {
  padding-top: 20px; position: relative;
  
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
}

.tree li {
  float: left; text-align: center;
  list-style-type: none;
  position: relative;
  padding: 20px 5px 0 5px;
  
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
}

/*We will use ::before and ::after to draw the connectors*/

.tree li::before, .tree li::after{
  content: '';
  position: absolute; top: 0; right: 50%;
  border-top: 1px solid #ccc;
  width: 50%; height: 20px;
}
.tree li::after{
  right: auto; left: 50%;
  border-left: 1px solid #ccc;
}

/*We need to remove left-right connectors from elements without 
any siblings*/
.tree li:only-child::after, .tree li:only-child::before {
  display: none;
}

/*Remove space from the top of single children*/
.tree li:only-child{ padding-top: 0;}

/*Remove left connector from first child and 
right connector from last child*/
.tree li:first-child::before, .tree li:last-child::after{
  border: 0 none;
}
/*Adding back the vertical connector to the last nodes*/
.tree li:last-child::before{
  border-right: 1px solid #ccc;
  border-radius: 0 5px 0 0;
  -webkit-border-radius: 0 5px 0 0;
  -moz-border-radius: 0 5px 0 0;
}
.tree li:first-child::after{
  border-radius: 5px 0 0 0;
  -webkit-border-radius: 5px 0 0 0;
  -moz-border-radius: 5px 0 0 0;
}

/*Time to add downward connectors from parents*/
.tree ul ul::before{
  content: '';
  position: absolute; top: 0; left: 50%;
  border-left: 1px solid #ccc;
  width: 0; height: 20px;
}

.tree li a{
  border: 1px solid #ccc;
  padding: 5px 10px;
  text-decoration: none;
  color: #666;
  font-family: arial, verdana, tahoma;
  font-size: 11px;
  display: inline-block;
  
  border-radius: 5px;
  -webkit-border-radius: 5px;
  -moz-border-radius: 5px;
  
  transition: all 0.5s;
  -webkit-transition: all 0.5s;
  -moz-transition: all 0.5s;
}

/*Time for some hover effects*/
/*We will apply the hover effect the the lineage of the element also*/
.tree li a:hover, .tree li a:hover+ul li a {
  background: #c8e4f8; color: #000; border: 1px solid #94a0b4;
}
/*Connector styles on hover*/
.tree li a:hover+ul li::after, 
.tree li a:hover+ul li::before, 
.tree li a:hover+ul::before, 
.tree li a:hover+ul ul::before{
  border-color:  #94a0b4;
}

PS: apart from the code, I also like the way the site shows it in action... really innovative.

Solution 5 - Javascript

If someone wants expandable/collapsible version of the treeview from Vitaliy Bychik's answer, you can save some time :)

http://jsfiddle.net/mehmetatas/fXzHS/2/

$(function () {
    $('.tree li').hide();
    $('.tree li:first').show();
    $('.tree li').on('click', function (e) {
        var children = $(this).find('> ul > li');
        if (children.is(":visible")) children.hide('fast');
        else children.show('fast');
        e.stopPropagation();
    });
});
