Installation

$ bower install bootstrap-tags

or

--> js files are located in dist/js, CSS in dist/css

Features

• Support for Bootstrap 2.3.2 and 3+
• Autosuggest (for typing or activated by pressing the down key when empty)
• Bootstrap Popovers (for extended information on a tag)
• Exclusions (denial of a specified list)
• Filters (allowance of only a specified list)
• Placeholder prompts
• Uses bootstrap button-[type] class styling (customizing your bootstrap will change tag styles accordingly)
• Extensible with custom functions (eg, before/after tag addition/deletion, key presses, exclusions)

<script src='path/to/bootstrap-tags/dist/js/bootstrap-tags.min.js'></script>

<div id="my-tag-list" class="tag-list"></div>
<script>
	$(function() {
		// If using Bootstrap 2, be sure to include:
		// Tags.bootstrapVersion = "2";
		$('#my-tag-list').tags({
			tagData:["boilerplate", "tags"],
			suggestions:["basic", "suggestions"],
			excludeList:["not", "these", "words"]

Some functions are chainable (returns a Tagger object), and can be used to move the data around outside of the plugin.

function	return type	description
hasTag(tag:string)	Boolean	whether tag is in tag list
getTags()	Array	a list of tags currently in the interface
getTagsWithContent()	Array	a list of javascript objects with a tag property and content property
getTag(tag:string)	String	returns tag as string
getTagWithContent(tag:string)	Object	returns object with tag and content property (popover)
addTag(tag:string)	Tagger	add a tag
renameTag(tag:string, newTag:string)	Tagger	rename one tag to another value
removeLastTag()	Tagger	removes last tag if it exists
removeTag(tag:string)	Tagger	removes tag specified by string if it exists
addTagWithContent(tag:string, popoverContent:string)	Tagger	Add a tag with associated popover content
setPopover(tag:string, popoverContent:string)	Tagger	update a tag's associated popover content, if that tag exists

Example:

var tags = $('#one').tags( {
	suggestions : ["here", "are", "some", "suggestions"],
	popoverData : ["What a wonderful day", "to make some stuff", "up so that I", "can show it works"],
	tagData: ["tag a", "tag b", "tag c", "tag d"],
	excludeList : ["excuse", "my", "vulgarity"],
} );
tags.addTag("tag e!!").removeTag("tag b").setPopover("tag c", "Changed popover content");
console.log(tags.getTags());

To reference a tags instance that you've already attached to a selector, (eg. $(selector).tags(options)) you can use $(selector).tags() or $(selector).tags(index)

Contributing

If you spot a bug, experience browser incompatibility, or have feature requests, please submit them here.

If you want to hack away to provide a new feature/bug-fix, please follow these guidelines:

• Make changes to the coffeescript and sass files, not js/css. This is to ensure that the next person who comes in and edits upstream from js/css will not overwrite your changes.
• Create a pull request for your feature branch, updating README documentation if necessary
