I have two choice columns in my list - Category and Sub-category respectively.

Now, if I select a value from Category, the choice values in the Sub-Category should display only the values I prefer.

Can we do this using jquery? And possibly can we do this without using Cascading Look up fields?

@Dheeraj try this code for dynamic dropdown binding

<script language="javascript" src="../SiteAssets/jquery-3.1.0.min.js" type="text/javascript"></script> 
<script language="javascript" src="../SiteAssets/jquery.SPServices-0.7.2.js" type="text/javascript">  </script> 
<script type="text/javascript">  
  $(document).ready(function() {
    relationshipList: "SubCategory",
    relationshipListParentColumn: "Category",
    relationshipListChildColumn: "Title",    
    parentColumn: "Category",
    childColumn: "SubCategory",
    debug: true

If you have pairing defined, you can use mapping method:

var map = new Object(); // or var map = {};
map[myKey1] = "subCat1,subCat2";
map[myKey2] = "subCat3,subCat4";

function get(k) {
    return map[k];

//Attach event with dropdown selector, of main category.

  var subCategory = $("#subCategorySelectId");
  subCategory.find('option').remove().end(); // To clear previous items
  var mappedValue = get(this.value); // to get all mapped items
  var subCategories = mappedValue.split(',');
     $.each(subCategories, function() { // populate sub category items
       options.append($("<option />").val(this.text).text(this.text));
  • Could you please tell me what is myKey1 and myKey2 here?

  • it will be your Main category option. Commented Feb 8, 2016 at 5:48

    You will need to actually hardcode Main category options, and respective sub categories, because both choice columns are in same list and there is no mapping defined as per your structure Commented Feb 8, 2016 at 5:49
