Bootstrap Tags Input w/ itemValue & freeinput

Bootstrap Tags Input is a jQuery plugin providing a Twitter Bootstrap user interface for managing tags. I have made a small feature addition in order to use object value/text with free input. This makes each freeinput tag addition attempt with a new event beforeFreeInputItemAdd

Difference

• beforeFreeInputItemAdd event
• When itemValue is set, freeInput can still be used

Example

var myTags = []

var tagToken = new Bloodhound({
    datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    local: [{'text': 'Choice1', 'value': 1}, {'text': 'Choice2', 'value': 2}, {'text': 'Choice3', 'value': 3}]
});

options = {
    itemValue: 'value',
    itemText: 'text',
    trimValue: true,
    freeInput: true,
    typeaheadjs: {
        hint: true,
        highlight: true,
        name: 'myinput',
        displayKey: 'text',
        source: tagToken.ttAdapter(),
    },
};

$('#myinput').tagsinput(options);

$('#myinput').on('beforeFreeInputItemAdd', function(event) {
    //event.item is the freeinput text
    // we should convert that into acceptable item
    // and change "cancel" to false that is default behaviour
    $.newTagIds_forThisElement==undefined ? $.newTagIds_forThisElement = [1000] : ""; // I would like my new addition tags start with index 1001
    lastId = $.newTagIds_forThisElement.pop();
    $.newTagIds_forThisElement.push(lastId);
    $.newTagIds_forThisElement.push(lastId+1);
    event.item = {'text': event.item, 'value': lastId+1};
    event.cancel = false;  
});

Warning

• Already imported tag list and new free input may collide because of new IDs
