Hide options in a variable

[John Vo1]

Is there   a script that can be place to remove options under a variable.   UI Policy will just hide the variable and that's not what I want.

For example:

If Remove User Access is selected for Type:

I want only N/A to show and not the other 2 options for Ready Only or Write.

Using a catalog client script, you can use the g_form.removeOption() method to show/hide your variables. In a catalog client script, the variables operate similar to fields on a standard form/table/record.

Chuck,

Can you give me an example of how the script would look like?

Thanks,

John

it would go something like this. Update variable names and values accordingly. This is all untested on my end.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {

  if (newValue === '') {

      return;

  }

          if (g_form.getValue('type') == 'Remove User Access')) {

                  g_form.removeOption('additional_information', 'Read only');

                    g_form.removeOption('additional_information', 'Write');

        }

}

Would this be a catalog client script under the catalog item?
