how to select multiple options from a search input with Jquery typeahead.js plugin

I am using jQuery Typeahead plugin. I have a search input and dropdown list containing different values as you see below
for example if I select the shipment report, I will see just the shipment data as you see below
I want to use the multiselect options instead of selecting just one value. I am following the demo example Hockey v2 . I have enable the multiselect in my script but it's still selecting just one value.
Any suggestions please what am I missing in my code ? Thank you.
var data = [{
"name": "country",
"id": "country",
"typeReport": "shipment"
}, {
"name": "customer name",
"id": "customer name",
"typeReport": "shipment"
}, {
"name": "order number",
"id": "order number",
"typeReport": "serial"
}, {

If you browse link as you mentioned "https://cdnjs.cloudflare.com/ajax/libs/jquery-typeahead/2.7.0/jquery.typeahead.js". There are no such type of attribute "multiselect".
It means that, you are using old version of type ahead script.
As per latest script "https://cdnjs.com/libraries/jquery-typeahead". Please see below are the example.

Kendo dropdownlist databound is called before dropdown item is set from the model

I have recently started learning KendoUI and have come up with this issue. I am trying to include a dropdownlist in kendo grid using MVVM approach. The grid has 3 columns- Checkbox, text and dropdownlist. I want to manually set the dropdownlist value based on whether the checkbox is checked or not. As an example here i am trying to set the Class as 'Class 3' if checkbox is unchecked. Even though index is set to 2, it gets reverted back to the class from the model at the end of the event dataBound. Can anyone help me with this? I need to forcefully set the dropdown index. Thank you.

How to create custom dropdownlist in kendo grid header column?

Actually my requirement is want to create custom dropdownlist in the column header of kendo grid. I don't down like nrwant to use filtler column. I just want to add normal dropdown in header. Please provide any example like that so that i can move forward on my task.
Thanks in advance...

In your column definition add a property like this:
headerTemplate: '<input id="dropdown" />'
Then after your grid initialization do:
$("#dropdown").kendoDropDownList({...init parameters...});
UPDATE: go to dojo.telerik.com and paste in the following code:
<div id="grid"></div>
<script>
$("#grid").kendoGrid({
columns: [
{
field: "ProductName",
title: "Product Name",
headerTemplate: '<input id="dropdown" />'
},
{ field: "UnitPrice", title: "Price", template: 'Price: #: kendo.format("{0:c}", UnitPrice)#' }
],
pageable: true,
dataSource: {
transport: {
read: {
url: "http://demos.telerik.com/kendo-ui/service/products",
dataType: "jsonp"
}
},
pageSize: 10
},
excelExport: function(e) {
var sheet = e.workbook.sheets[0];
var template = kendo.template(this.columns[1].template);
for (var i = 1; i < sheet.rows.length; i++) {
var row = sheet.rows[i];
var dataItem = {
UnitPrice: row.cells[1].value
};
row.cells[1].value = template(dataItem);
}
}
});
$("#dropdown").kendoDropDownList({
optionLabel: 'Choose a value...',
dataTextField: 'description',
dataValueField: 'id',
dataSource:{
data: [{id: 1, description: 'One'},{id: 2, description: 'Two'}]
},
change: function(e){
//do whatever you need here, for example:
var theGrid = $("#grid").getKendoGrid();
var theData = theGrid.dataSource.data();
$(theData).each(function(index,item){
item.ProductName = e.sender.text();
});
theGrid.dataSource.data(theData);
}
});

Select2.js: why is id the same as text on change for removed?

JSfiddle: http://jsfiddle.net/cjVSj/
I have a simple select2 with the range of possible tags set by the tags option and the preloaded tags set by values in the input field in the html.
When the on change event fires on the select2, the removed item seems to lose its id, reporting instead its text value.
To see the problem, adding a tag (e.g. west) correctly reports the added.id, but removing the existing east tags reports id = east, not 1356.
Any insight into how to gain access to the id of a tag upon removal?
HTML:
<script>
var tags = [{ "id": 1354, "text": "north", "restricted": false
}, {"id": 1355, "text": "south", "restricted": false
}, {"id": 1356, "text": "east", "restricted": false
}, {"id": 1357, "text": "west", "restricted": false
}];
</script>tags:
<input type="text" id="mytags" value="east" />
JS:
$(document).ready(function () {
$('#mytags').select2({
placeholder: 'Search',
allowClear: true,
minimumInputLength: 2,
multiple: true,
tags: tags,
tokenSeparators: [','],
});
$('#mytags').on("change", function (e) {
console.log("change " + JSON.stringify({
val: e.val,
added: e.added,
removed: e.removed
}));
if (e.added) {
alert('added: ' + e.added.text + ' id ' + e.added.id)
} else if (e.removed) {
alert('removed: ' + e.removed.text + ' id ' + e.removed.id)
}
});
});

There was an issue with your select2 declaration and syntax.
Further more, if you entered any other text, say "eas" or "test", your piece of code reflected that as it is. Check this scenario.
Updated fiddle: http://jsfiddle.net/ZBf5H/
To be specific, you did not give appropriate mapping to your tags. Please find how to access remote data in select 2 from here
The change of code is as below:
$(document).ready(function() {
var data=[{id:1354,text:'north',restricted:false},
{id:1356,text:'east',restricted:false},
{id:1357,text:'west',restricted:false},
{id:1355,text:'south',restricted:false}];
function format(item)
{ return item.text; }
$('#mytags').select2({
placeholder: 'Search',
allowClear: true,
minimumInputLength: 2,
multiple: true,
tags: tags,
tokenSeparators: [','],
data:{ results: data, text: 'text' },
formatSelection: format,
formatResult: format
});
Let me know if this works for you.

Ok... I've got a working solution, but I still don't exactly understand the difference between select2's tags and data options....
JSfiddle: http://jsfiddle.net/7e8Pa/
I'm initializing select2 with a list of all possible tags via the data option from an array, then selecting those for preloading: the initSelection function checks for ids in the and looks them up in the data array (the pre-stored one, not Select2's). Last, new tags may be added (the createSearchChoice does this). To hook this to my server, I'm just going to insert ajax calls where noted below in the on-change event handler (which gets called after createSearchChoice, and can overwrite the field values for the new object set in createSearchChoice).
JS:
function findWithAttr(array, attr, value) {
for (var i = 0; i < array.length; i += 1) {
if (array[i][attr] == value) {
return array[i];
}
}
}
$(document).ready(function () {
function format(item) {
return item.text;
}
$('#mytags').select2({
placeholder: 'Search',
minimumInputLength: 2,
multiple: true,
//tags: tags,
tokenSeparators: [','],
data: {
results: tags,
text: 'text'
},
initSelection: function (element, callback) {
var data = [];
$($('#mytags').val().split(",")).each(function (i) {
var o = findWithAttr(tags, 'id', this);
if (o) {
data.push({
id: o.id,
text: o.text
});
} else {
console.log("findWithAttr returned none; likely invalid id");
}
});
console.log("data = " + JSON.stringify(data));
callback(data);
},
createSearchChoice: function (term, data) {
console.log("create");
if ($(data).filter(function () {
return this.text.localeCompare(term) === 0;
}).length === 0) {
// call $.post() to add this term to the server, receive back id
// return {id:id, text:term}
// or detect this shiftiness and do it below in the on-change
return {
id: -1,
text: term
};
}
},
formatSelection: format,
formatResult: format
});
$('#mytags').on("change", function (e) {
console.log("change " + JSON.stringify({
val: e.val,
added: e.added,
removed: e.removed
}));
if (e.added) {
alert('added: ' + e.added.text + ' id ' + e.added.id);
//modifying the id here overrides what is assigned above in createSelection
e.added.id = 5;
} else if (e.removed) {
alert('removed: ' + e.removed.text + ' id ' + e.removed.id);
}
var selections = (JSON.stringify($('#mytags').select2('data')));
$('#selectedText').text(selections);
});
});
HTML:
<script>
var tags = [{
"id": 1354,
"text": "north",
"restricted": false
}, {
"id": 1355,
"text": "south",
"restricted": false
}, {
"id": 1356,
"text": "east",
"restricted": false
}, {
"id": 1357,
"text": "west",
"restricted": false
}];
</script>
<p>tags:
<input type="text" id="mytags" value="1355" style="width:80%" />

<p>Selected Options: <span id="selectedText"></span>

autocomplete searches work, but not gets selected

Input text boxes are created dynamically via jquery. Autocomplete works well. But when I select an item its value is not rendered properly, May I know where am I missing here ?
Jquery
$(function() {
var projects = [
{
"label": "ajax",
"value": "1003",
"desc": "foriegn"
},
{
"label": "jquery",
"value": "1000",
"desc": "dd"
},
{
"label": "wordpress theme",
"value": "1000",
"desc": "h"
},
{
"label": "xml",
"value": "1000",
"desc": "j"
} ];
$("#addButton");
var counter = 13;
$("#addButton").click(function() {
var newTextBoxDiv = $(document.createElement('div'))
.attr("id", 'TextBoxDiv' + counter);
var roleInput = $('<input/>', {
type: 'text',
placeholder: 'Role',
name: 'Role' + counter,
id: 'project-description' + counter
});
var searchInput = $('<input/>', {
type: 'text',
placeholder: 'search',
name: 'search' + counter,
id: 'project' + counter
});
var hidd = $('<input/>', {
type: 'hidden',
name: 'searchhid' + counter,
id: 'project-id' + counter
});
newTextBoxDiv.append(roleInput).append(searchInput).append(hidd);
newTextBoxDiv.appendTo("#TextBoxesGroup");
$("#project" + counter).autocomplete({
minLength: 0,
source: projects,
focus: function(event, ui) {
$("#project" + counter).val(ui.item.label);
return false;
},
select: function(event, ui) {
$("#project" + counter).val(ui.item.label);
$("#project-id" + counter).val(ui.item.value);
$("#project-description" + counter).val(ui.item.value);
$("#project-icon" + counter).attr("src", "images/" + ui.item.icon);
return false;
}
})
counter++;
});
});
`
Html is below
<div id="project-label"></div>
<input id="project" />
<input type="hidden" id="project-id" />
<input type="text" disabled="disabled" id="project-description"></p>
<div id='TextBoxesGroup'>
<div id="TextBoxDiv1" class="form-inline control-group">
</div>
</div>
<input type='button' value='Add' id='addButton' />
Please tell me what am I missing in this piece of code.

I think it's a JavaScript error. Your select event from the autocomplete looks for $("#project-icon" + counter), but I don't see that element being rendered anywhere. Also, when trying to set the src attribute of that element, you reference ui.item.icon, but your array of values doesn't contain that property.
