Show/Hide choices of field based on selection of another field choice

[Evan2]

Hi Friends,

I an trying to show/hide choice of request type based on the choice selected for the field Select request Item on service portal.

Example:-

If Select request Item= Card Swipe Unit

then- Request Type should only show Install card swipe unit as choice.

PFB the screenshot for reference and help me how to achieve this.

Regards,

Evan

Hi there,

Is request type for example a Reference type variable? And is there a relation with the Request type If so, you could use a reference qualifier? Have you tried that / investigated that already?

If my answer helped you in any way, please then mark it as helpful.

Kind regards,
Mark

Hi Evan,

you would require onchange client script on the select item variable; sample script below

function onChange(control, oldValue, newValue, isLoading) {
   if (isLoading) {
      return;
   }

g_form.clearOptions('request_type');

if(newValue == 'Card Swipe Unit'){

g_form.addOption('request_type', choicevalue, choiceLabel);
g_form.addOption('request_type', choicevalue, choiceLabel);

}

}

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.

Hi Evan,

So is it giving the alert at line 12?

Did you check the choice value for request_type variable?
