Not only manage tags on the form but in the article or simply fetch(list) tags without management.
Chose tags only from suggestions or create new values
Set who can delete or create tags

How to use

<!DOCTYPE html>
<html>
<head>
    <title>Bootstrap tags - pills UI component</title>
</head>
<body>
    <div id="bs-tags"></div>
</div>

<script type="text/javascript" src="components/jquery.min.js"></script>
<script type="text/javascript" src="components/bootstrap.bundle.js"></script>
<script type="text/javascript" src="components/bootstrap3-typeahead.js"></script>
<script type="text/javascript" src="components/jquery.color.js"></script>
<script type="text/javascript" src="js/bootstrap-tags.js"></script>
<script type="text/javascript">
    $('#bs-tags').tags({});
</script>
</body>
</html>

The minimal requirements are Bootstrap, jQuery and bootstrap3-typeahead loaded and bootstrap-tags.js. There is not css file for this element. Just use default style here and you can make your adjustment to it. It is already in roadmap to make this element themable.

Feed format

As for default values or typeahead suggestions the format is the same. It is an array of values. Values can be string or object or mixed.

[
    {
        "id": "1",
        "name": "Apple",
        "suggest": "Apple (5)",
        "num": 5
    },
    {
        "id": "3",
        "name": "Mango",
        "suggest": "mango (10)",
        "url": "/",
        "title": "Click here to see all articles of only Mango's"
    },
    "Banana"
]

Object may contain following properties

Property	Required	Description
`id`	Yes	Required only if object. If it is a string, the same value for `text` and `id` will be used.
`name`	Yes	Used as tag text.
`suggest`	No	If not set `text` will be used. This property is used to display in typeahead suggestions.
`num`	No	If set, number will be shown after the text.

        number: ' <sup><small>{0}</small></sup>'
	}
});

Events

With extended events API you can affect almost anything.

onLoadDefaults(values)

This method is triggered right before fetch tags pills and after values_url has been fetched. What you return will be used to pre-populate component with tags/pills.

values - List of items already populated with values and values_url options. Thus you basically have to merge values if you want to add some values.

Example

$('#bs-tags').tags({
	onLoadDefaults:function(values){
    	return $.merge(values,["apple", "banana"]);
	}
});

onRemove(pill)

Triggered before removing HTML element of tag/pill.

pill - HTML element. headsup: every HTML element has data-tag-id attribute populated from item.id of the tags feed element.

Example

$('#bs-tags').tags({
	onRemove: function(pill){
    	var id = pill.data('tag-id');
    	// do something...
	}
});

onError(num, msg)

This alerts error message by default. But if you have your own error management system you can use this callback.

num - error number.
msg - error text.

Error	Text
10	You have reached limit of only {0} tags to be added.
11	Not correct object format to create tag/pill

### onBeforeAdd(pill, item)

This event is triggered before HTML element appended to pills list. This method has to return pill.

pill - an HTML element ready to be appended to list.
item - tag object with all properties like is, text, suggest, url, ... It will also contain all other custom properties you add to feed.

### onLoadSuggestions(values)

This event is triggered after suggestions_url has been fetched right before show suggestions in typeahead.

values - List of items already populated with suggestions and suggestions_url options. Thus you basically have to merge values if you want to add some values.

The same as onLoadDefaults but for typeahead suggestions.

onDuplicate

This event is triggered as a duplicate tag is being added. This method can return true or false. If the method returns true the the duplicate tag is added, however, if the method returns false the duplicate tag will not be added. By default the tag is not added and a small visual effect is used to alert the user. Two parameters are passed to the callback:

original - The first tag in the list that is equal to the tag that is being added
duplicate - The value of the tag that is being added

Example

$('#bs-tags').tags({
    onDuplicate: function(original, duplicate){
        //do something...
    }
});

onBeforeRemove

This event is triggered before a tag is removed. The function for this event should return true or false. If the function returns true then the tag is removed, however, if the function returns false then the tag will not be removed. If there is a removal request to the server, it will happen after this function returns true. By default, the tag is removed, but this event can be useful if you want to make certain tags unremovable. One parameter is passed to the callback:

pill - HTML element. headsup: every HTML element has data-tag-id attribute populated from item.id of the tags feed element.

Example

$('#bs-tags').tags({
    onBeforeRemove: function(pill){
        if($(pill).data('tag-id') === 'Apple') {
            return false; // "Apple" tags are unremovable.
        } else {
            return true;
        }
    }
});

Examples

Load default values

There are 3 methods to load default values or pre-populate tags/pills. Methods are listed in order of execution.

First method is to pass default values as values option.
```
 $('#bs-tags').tags({values:["banana", "apple"]});
```
Second method to provide URL where through GET it will fetch default values
```
 $('#bs-tags').tags({values_url:"urls/defaults.json"});
```

And last method is to use callback function

 $('#bs-tags').tags({
     onLoadDefaults:function(values){
         return $.merge(values,["apple", "banana"]);
     }
 });

Here values contain already loaded values with previous methods.

Or you can use all methods at once. All values will be merged.

Remove tag/pill

First there is can_delete option to allow or disallow tags removing.

$('#bs-tags').tags({can_delete:true});

This will allow simply remove tag HTML element with hidden <input>. But if you want callback on the event you can use onRemove(pill) callback.

$('#bs-tags').tags({
    can_delete: true,
    onRemove(pill) {
        // do something...
    }
});

Where pill is an HTML element.

And another way to control removal, is to set special URL where POST request will be sent with id parameter.

$('#bs-tags').tags({can_delete: true, remove_url: 'http://mysite.com/removetag.php'});

Load suggestions

There are 3 methods to load suggestions to typeahead dropdown.

First method is to pass default values as suggestions option.
```
 $('#bs-tags').tags({suggestions:["banana", "apple"]});
```
Second method to provide URL where through GET it will fetch default values
```
 $('#bs-tags').tags({suggestions_url:"urls/defaults.json"});
```

And last method is to use callback function

 $('#bs-tags').tags({
     onLoadSuggestions: function(values){
         return $.merge(values,["apple", "banana"]);
     }
 });

Here values contain already loaded values with previous methods.

Roadmap

do not show in suggestion elements that are already added
themable interface. jQuery UI theme.
