Hi All,

I have a short description field type list  which consists of 20 choices/ values

I should allow/restrict users to enter/select any 5 value/choices in short description field

Hi,

something like this in onChange of that field

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

	if (newValue.toString().split(',').length > 5) {
		alert('Please select only 5 values');
	} 
}

OR

you can also use onSubmit

function onSubmit(){

	if (g_form.getValue('fieldName').toString().split(',').length > 5) {
		alert('Please select only 5 values');
		return false;
	} 
}
