Hide options from OptionSet using JavaScript in Dynamics 365 CRM

Many times, you might not want to show all Options from an OptionSet while it is on a form. So, here’s how you can hide Options from OptionSet using JavaScript in Dynamics 365 CRM!


Let’s see the below scenario where these are the options you already see –

  1. You see, there are 3 options for this OptionSet on Contact Form.

  2. Now, you want to hide “Platinum” as an option when a Form loads. So, let’s see how this done.

  3. Now, we can use this information to hide the Option Platinum. We’ll write JS script on the OnLoad of the Contact form.

JS Code

Here’s a JS code sample which will hide the options which you don’t need to display.

  1. Below is the code which you need to register OnLoad of the Contact form and also pass the Context as first parameter –

  2. And when you register it OnLoad, it should look like below –


oContactCustomization = {
    hidePlatinumGrade: function (context) {
        "use strict"; debugger;
        var formContext = context.getFormContext();
        var gradeOptionSet = formContext.getControl("new_grade");
        if (gradeOptionSet !== null) {

Here, you get the OptionSet using getControl(); method and then use the variable to then have removeOption(<OptionSet Value>);


Now, when you load the form, you’ll see the option is no longer visible –

Hope this helps!
