Show/hide section with onChange client script

[joaosantos]

I have a requirement to only show "Closure Information" section when the state is closed. For that i have the following code but when i change state from closed to a different state, the section is still displayed

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

    if (isLoading || newValue === '') {

          return;

    }

  var state = g_form.getValue('state');

if(state == "7"){

g_form.setSectionDisplay('closure_information',true);

}

if (state != "7"){

g_form.setSectionDisplay('closure_information',false);

}

}

And also make sure you dont have any mandatory fields over there. It will not work if you have any
