How to show and hide one choice value based on category selection

[VIKAS MISHRA]

If someone select category "A" on the portal then only sub category "X" should be visible. 

And if user unselect the category from A to somthing else then sub category "X" should again be hidden, 

Please suggestion how to do it

Hi @VIKAS MISHRA 

You need to to write the client script for the same. 

As you are hiding the value.

I am writing below mentioned script but that one

function onChange(control, oldValue, newValue, isLoading) {
  if (isLoading ) {
	if(g_form.getValue('category') != 'Business Application'){
		g_form.removeOption('subcategory', 'Costa Loyalty – Poland');
	}
       return;
    }

var cat = g_form.getValue('category');
var subcat = g_form.getValue('subcategory');
if (cat != 'Business Application') {
g_form.removeOption('subcategory', 'Costa Loyalty – Poland');
}}

is not working.

Hi Vikas,

To avoid scripting, this can also be done using dictionary dependency. You can add dependencies in sub-category field for required category values respectively.

Please mark it helpful if I could help with your query.
