Bootstrap Tags Input

jQuery plugin providing a Twitter Bootstrap user interface for managing tags

Markup

Just add data-role="tagsinput" to your input field to automatically change it to a tags input field.

<input type="text" value="Amsterdam,Washington,Sydney,Beijing,Cairo" data-role="tagsinput" placeholder="Add tags" />
statementreturns
$("input").val()
$("input").tagsinput('items')

True multi value

Use a <select multiple /> as your input element for a tags input, to gain true multivalue support. Instead of a comma separated string, the values will be set in an array. Existing <option /> elements will automatically be set as tags. This makes it also possible to create tags containing a comma.

<select multiple data-role="tagsinput">
  <option value="Amsterdam">Amsterdam</option>
  <option value="Washington">Washington</option>
  <option value="Sydney">Sydney</option>
  <option value="Beijing">Beijing</option>
  <option value="Cairo">Cairo</option>
</select>
statementreturns
$("select").val()
$("select").tagsinput('items')

Typeahead

<input type="text" value="Amsterdam,Washington" data-role="tagsinput" />
<script>
$('input').tagsinput({
  typeahead: {
    source: function(query) {
      return $.getJSON('citynames.json');
    }
  }
});
</script>
statementreturns
$("input").val()
$("input").tagsinput('items')

Objects as tags

Instead of just adding strings as tags, bind objects to your tags. This makes it possible to set id values in your input field's value, instead of just the tag's text.

<input type="text" />
<script>
$('input').tagsinput({
  itemValue: 'value',
  itemText: 'text',
  typeahead: {
    source: function(query) {
      return $.getJSON('cities.json');
    }
  }
});

$('input').tagsinput('add', { "value": 1 , "text": "Amsterdam"  });
$('input').tagsinput('add', { "value": 4 , "text": "Washington" });
$('input').tagsinput('add', { "value": 7 , "text": "Sydney"     });
$('input').tagsinput('add', { "value": 10, "text": "Beijing"    });
$('input').tagsinput('add', { "value": 13, "text": "Cairo"      });
</script>
statementreturns
$("input").val()
$("input").tagsinput('items')

Categorizing tags

You can set a fixed css class for your tags, or determine dynamically by provinding a custom function.

<input type="text" />
<script>
$('input').tagsinput({
  tagClass: function(item) {
    switch (item.continent) {
      case 'Europe'   : return 'label label-info';
      case 'America'  : return 'label label-important';
      case 'Australia': return 'label label-success';
      case 'Africa'   : return 'badge badge-inverse';
      case 'Asia'     : return 'badge badge-warning';
    }
  },
  itemValue: 'value',
  itemText: 'text',
  typeahead: {
    source: function(query) {
      return $.getJSON('cities.json');
    }
  }
});

$('input').tagsinput('add', { "value": 1 , "text": "Amsterdam"   , "continent": "Europe"    });
$('input').tagsinput('add', { "value": 4 , "text": "Washington"  , "continent": "America"   });
$('input').tagsinput('add', { "value": 7 , "text": "Sydney"      , "continent": "Australia" });
$('input').tagsinput('add', { "value": 10, "text": "Beijing"     , "continent": "Asia"      });
$('input').tagsinput('add', { "value": 13, "text": "Cairo"       , "continent": "Africa"    });
</script>
statementreturns
$("input").val()
$("input").tagsinput('items')

AngularJS support

Include bootstrap-tagsinput-angular.js and register the 'bootstrap-tagsinput' in your Angular JS application to use the bootstrap-tagsinput directive.

<bootstrap-tagsinput
  ng-model="cities"
  typeahead-source="queryCities"
  tagclass="getTagClass"
  itemvalue="value"
  itemtext="text">
</bootstrap-tagsinput>

<script>
angular.module('AngularExample', ['bootstrap-tagsinput'])
  .controller('CityTagsInputController',
    function CityTagsInputController($scope) {
      // Init with some cities
      $scope.cities = [
        { "value": 1 , "text": "Amsterdam"   , "continent": "Europe"    },
        { "value": 4 , "text": "Washington"  , "continent": "America"   },
        { "value": 7 , "text": "Sydney"      , "continent": "Australia" },
        { "value": 10, "text": "Beijing"     , "continent": "Asia"      },
        { "value": 13, "text": "Cairo"       , "continent": "Africa"    }
      ];

      $scope.queryCities = function(query) {
        return $http.get('cities.json');
      };

      $scope.getTagClass = function(city) {
        switch (city.continent) {
          case 'Europe'   : return 'badge badge-info';
          case 'America'  : return 'label label-important';
          case 'Australia': return 'badge badge-success';
          case 'Africa'   : return 'label label-inverse';
          case 'Asia'     : return 'badge badge-warning';
        }
      };
    }
  );
</script>
statementreturns
$scope.cities
{{cities}}
$("select").val()
$("select").tagsinput('items')
option description
tagClass

Classname for the tags, or a function returning a classname

$('input').tagsinput({
  tagClass: 'big'
});
$('input').tagsinput({
  tagClass: function(item) {
    return (item.length > 10 ? 'big' : 'small');
  }
});
itemValue

When adding objects as tags, itemValue must be set to the name of the property containing the item's value, or a function returning an item's value.

$('input').tagsinput({
    itemValue: 'id'
});
$('input').tagsinput({
  itemValue: function(item) {
    return item.id;
  }
});
itemText

When adding objects as tags, you can set itemText to the name of the property of item to use for a its tag's text. You may also provide a function which returns an item's value. When this options is not set, the value of itemValue will be used.

$('input').tagsinput({
  itemText: 'label'
});
$('input').tagsinput({
  itemText: function(item) {
    return item.label;
  }
});
confirmKeys

Array of keycodes which will add a tag when typing in the input. (default: [13], which is ENTER)

$('input').tagsinput({
  confirmKeys: [13, 44]
});
maxTags

When set, no more than the given number of tags are allowed to add (default: undefined). When maxTags is reached, a class 'bootstrap-tagsinput-max' is placed on the tagsinput element.

$('input').tagsinput({
  maxTags: 3
});
freeInput

Allow creating tags which are not returned by typeahead's source (default: true)

This is only possible when using string as tags. When itemValue option is set, this option will be ignored.
$('input').tagsinput({
  typeahead: {
    source: ['Amsterdam', 'Washington', 'Sydney', 'Beijing', 'Cairo'],
    freeInput: true
  }
});
typeahead

Object containing typeahead specific options

source

An array (or function returning a promise or array), which will be used as source for a typeahead.

$('input').tagsinput({
  typeahead: {
    source: ['Amsterdam', 'Washington', 'Sydney', 'Beijing', 'Cairo']
  }
});
$('input').tagsinput({
  typeahead: {                  
    source: function(query) {
      return $.get('http://someservice.com');
    }
  }
});
onTagExists

Function invoked when trying to add an item which allready exists. By default, the existing tag hides and fades in.

$('input').tagsinput({
  onTagExists: function(item, $tag) {
    $tag.hide.fadeIn();
  }
});
