Multi value Lookup Columns in SharePoint

I couldn't find anything obvious for accessing SharePoint Multi-value lookup columns and filtering the values so chucked this together, hopefully useful for someoneπŸ˜ƒ
In continuation to my previous article on Lookup Columns, we are going to learn about Multi-value lookup columns in SharePoint.
At the end of this article, I am going to give a bonus to the readers of this article 😊
Let's go ahead and create two source lists for this demo:
1. States 
2. Cities (State is a lookup column from States list)
3. The third list will be used to implement the Multi-value lookup column and also we are going to implement filtering multi-value lookup columns in this article. I have created a list named "Multi value lookup demo" which has State and City as lookup value from the first two lists created. Make sure, you select Allow multiple values options as shown below:

The new item form without filtering looks as shown below:
Following are the functionalities to be implemented & issues/challenges needs to be considered while implementing filtering multi-value lookup columns in SharePoint:
1. An option can be double clicked to select or clicked Add button to select a value
2. An option can be double clicked to deselect or clicked Remove button to deselect a value
3. More than one option can be selected and can be bulk added to the selected values
4. The JQuery implemented should satisfy the above conditions while filtering
5. When State is selected, the values of Cities should get filtered. In the same way, when a value from the deselected then the values from Cities should be removed
I have added a Script Editor web part in New item form and added JQuery as reference. Also, added the JS code which will implement the filtering functionality.
If you want to implement the same functionality in Edit item form, following the same steps just mentioned above.
I have used CAML query to do the filtering functionality which is shown below:
$(document).ready(function () {
    //Call multi-value lookup function on selecting State
    $("select[title='State possible values']").dblclick(function () {
    //Call multi-value lookup function on removing State
    $("select[title='State selected values']").dblclick(function () {
    //Call multi-value lookup function on clicking Add - State
    $("input[value='Add >'][id^='State_']").click(function (){
    //Call multi-value lookup function on clicking Remove - State
    $("input[value='< Remove'][id^='State_']").click(function () {
function multiValueLookup() {
    var items = "";
    var citiesListName = "Cities";
    $("select[title='City possible values'] option").remove();
    $("select[title='State selected values'] option").each(function (i) {
        var clientContext = new SP.ClientContext.get_current();
        var oList = clientContext.get_web().get_lists().getByTitle(citiesListName);
        var camlQuery = new SP.CamlQuery();
        camlQuery.set_viewXml("<View><Query><OrderBy><FieldRef Name='Title' /></OrderBy><Where><Eq><FieldRef Name='State' LookupId='TRUE'/><Value Type='Lookup'>" + $(this).val() + "</Value></Eq></Where></Query></View>");
        var items = oList.getItems(camlQuery);
        clientContext.executeQueryAsync(success, failure);
        function success() {
            var pn2 = "";
            var pn1 = "";
            var ListEnumerator = items.getEnumerator();
            while (ListEnumerator.moveNext()) {
                var currentItem = ListEnumerator.get_current();
                if (currentItem.get_item('Title') != null) {
                    var pn1 = currentItem.get_item('Title');
                    if (pn2 != pn1) {
                        items = "<option value='" + currentItem.get_item('ID') + "' title='" + pn1 + "'>" + pn1 + "</option>";
                        $("select[title='City possible values']").append(items);
                        pn2 = pn1;
        function failure(sender, args) {
            // alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());

The above code is self explanatory and I have added few screenshots below for reference:
When an value is selected
When an value is deselected
The added value in the multi-value lookup demo list
Cool isn't it? 😊 Very simple as well.
If you have read my previous article on Cascading Lookup Columns in SharePoint, you would have noticed that I have implemented the functionality using REST API.
You may think why I didn't implement multi-value lookup column using REST API? so the bonus is here. I have implemented the above functionality using REST API as well. I will add the code in download link and you can follow either of the way to implement this functionality 😎
This is tested in SharePoint Online and I am sure it should work for SharePoint 2013, 2016 & 2010 as well.

  1. Very Cool! I noticed you mentioned JSLink also, I just started working with that.

  2. Hi there! This is really cool. I was able to use this on our SharePoint.
    I now wanted to do also a form like this where the first field (e.g. State) is a single-value dropdown field and the second field (cities) the same as here - multi-value checkbox.
    The problem is that I can't figure out how to adjust the script, so the options for cities are filtered based on the selection made in state. I also checked your other post (http://sharepoint-works.blogspot.com/2017/06/cascading-drop-down-in-sharepoint.html) and tried to figure it out, but unfortunately I am unable to make it work.
    Would you know how I need to adjust the script in order to make this work?

  3. Hello,
    It's working for Default Forms...But when I add the same code on my CustomForm not working...

  4. The file providing the REST API as well as other downloadable content is no longer accessible. Is it possible to make this content available some other way? Thanks.

  5. hi,
    This is really great.
    I have a different requirement where I want to filter multi-select lookup column based on dropdown.
    Can you give any suggestions to implement this scenario?
