A prototype version of my jQuery based Tree View for Twitter Bootstrap
The project has very few dependencies, but you will need the following.
Npm:
$ npm install react-bootstrap-treeviewBower:
$ bower install react-bootstrap-treeviewManual:
Old fashion, downloadable files can be found here
Include the correct styles, it's mainly just bootstrap but we add a few tweaks as well.
<!-- Required CSS -->
<link href="path/to/bootstrap.css" rel="stylesheet">
<link href="path/to/react-bootstrap-treeview.css" rel="stylesheet">Add required libraries.
<!-- Required JavaScript -->
<script src="path/to/react.js"></script>
<script src="path/to/react-bootstrap-tree.js"></script>Then, a basic initialization would look like.
React.render(
<TreeView data={data} />,
document.getElementById('treeview')
);Putting it all together a minimal implementation might look like this.
<html>
<head>
<title>React + Bootstrap Tree View</title>
<link href="path/to/bootstrap.css" rel="stylesheet">
<link href="path/to/react-bootstrap-treeview.css" rel="stylesheet">
</head>
<body>
<div class="container">
<h1>React + Bootstrap Tree View</h1>
<br/>
<div class="row">
<div id="treeview"></div>
</div>
</div>
<script src="path/to/react.js"></script>
<script src="path/to/JSXTransformer.js"></script>
<script src="path/to/react-bootstrap-treeview.js"></script>
<script type="text/jsx">
React.render(
<TreeView data={data} />,
document.getElementById('treeview')
);
</script>
</body>
</html>In order to define the hierarchical structure needed for the tree it's necessary to provide a nested array of JavaScript objects.
Example
var tree = [
{
text: "Parent 1",
nodes: [
{
text: "Child 1",
nodes: [
{
text: "Grandchild 1"
},
{
text: "Grandchild 2"
}
]
},
{
text: "Child 2"
}
]
},
{
text: "Parent 2"
},
{
text: "Parent 3"
},
{
text: "Parent 4"
},
{
text: "Parent 5"
}
];At the lowest level a tree node is a represented as a simple JavaScript object. This one required property text will build you a tree.
{
text: "Node 1"
}If you want to do more, here's the full node specification
{
text: "Node 1",
icon: "glyphicon glyphicon-stop",
color: "#000000",
backColor: "#FFFFFF",
href: "#node-1",
state: {
expanded: true,
selected: true
},
tags: ['available'],
nodes: [
{},
...
]
}The following properties are defined to allow node level overrides, such as node specific icons, colours and tags.
String Mandatory
The text value displayed for a given tree node, typically to the right of the nodes icon.
String Optional
The icon displayed on a given node, typically to the left of the text.
For simplicity we directly leverage Bootstraps Glyphicons support and as such you should provide both the base class and individual icon class separated by a space.
By providing the base class you retain full control over the icons used. If you want to use your own then just add your class to this icon field.
String Optional
The foreground color used on a given node, overrides global color option.
String Optional
The background color used on a given node, overrides global color option.
String Optional
Used in conjunction with global enableLinks option to specify anchor tag URL on a given node.
Object Optional
Describes a node's initial state.
Boolean Default: false
Whether or not a node is expanded i.e. open. Takes precedence over global option levels.
Boolean Default: false
Whether or not a node is selected.
Array of Strings Optional
Used in conjunction with global showTags option to add additional information to the right of each node; using Bootstrap Badges
Options allow you to customise the treeview's default appearance and behaviour. They are passed to the react component as properties on initialization.
// Example: initializing the treeview
// expanded to 5 levels
// with a background color of green
React.render(
<TreeView data={data}
levels={5}
backColor={"green"} />,
document.getElementById('treeview')
);The following is a list of all available options.
Array of Objects. No default, expects data
This is the core data to be displayed by the tree view.
String, any legal color value. Default: inherits from Bootstrap.css.
Sets the default background color used by all nodes, except when overridden on a per node basis in data.
String, any legal color value. Default: inherits from Bootstrap.css.
Sets the border color for the component; set showBorder to false if you don't want a visible border.
String, class name(s). Default: "glyphicon glyphicon-minus" as defined by Bootstrap Glyphicons
Sets the icon to be used on a collapsible tree node.
String, any legal color value. Default: inherits from Bootstrap.css.
Sets the default foreground color used by all nodes, except when overridden on a per node basis in data.
String, class name(s). Default: "glyphicon" as defined by Bootstrap Glyphicons
Sets the icon to be used on a tree node with no child nodes.
Boolean. Default: false
Whether or not to present node text as a hyperlink. The href value of which must be provided in the data structure on a per node basis.
String, class name(s). Default: "glyphicon glyphicon-plus" as defined by Bootstrap Glyphicons
Sets the icon to be used on an expandable tree node.
Boolean. Default: true
Whether or not to highlight the selected node.
Integer. Default: 2
Sets the number of hierarchical levels deep the tree will be expanded to by default.
String, class name(s). Default: "glyphicon glyphicon-stop" as defined by Bootstrap Glyphicons
Sets the default icon to be used on all nodes, except when overridden on a per node basis in data.
String, any legal color value. Default: '#428bca'.
Sets the background color of the selected node.
String, any legal color value. Default: '#FFFFFF'.
Sets the foreground color of the selected node.
Boolean. Default: true
Whether or not to display a border around nodes.
Boolean. Default: false
Whether or not to display tags to the right of each node. The values of which must be provided in the data structure on a per node basis.
