Laravel form using LaravelCollection to redirect to URL with parameter when dropdown selected

Question

In my blade I have the following dropdown list

{!! Form::select('plans', $named_plans, null,['class' => 'form-control'] ) !!}

which is populated by a list named $named_plans passed by the controller. So far so good.

I need to take the value selected by the user from the dropdown and add it as a parameter to a URL. I can't figure out (and the LaravelCollective documentation is minimal at best) how to append the selected string to a URL (or route) and redirect the user there. Similar to how a dropdown menu works.

For instance, if the user selected "foo" from the dropdown, I want to send them to mylaravelsite/public/displaypage/foo. I have a route that will process displaypage/{foo} just fine if I could just code for the redirect.

Any suggestions would be very helpful.

I'm using Laravel 5.5 with PHP 7 on XAMPP

First take the value of selectbox option and add the attribute action to the form

$('#selectboxid').change(function(){
    var optionSelected = $("option:selected", this);
    optionValue = this.value;
    $('#idoftheform').attr('action','public/displaypage/'+optionValue);
});
