toggle slide open hidden div and slide close open divs at same time

toggle slide open hidden div and slide close open divs at same time

Trying to learn the basics... Here is a script for three toggle buttons that each when clicked open their corresponding divs. Fine. Now how does one go about automatically closing an open div when clicking on a new 'toggler' that opens it's div? I see other posts about this very question, but I'm just not grasping the logic.

jQuery(document).ready(function($) {
        $("#toggle1").click(function () {
            $("#toggle1div").toggle("drop", {direction:"right"}, 500);
        });
        $("#toggle2").click(function () {
            $("#toggle2div").toggle("drop", {direction:"right"}, 500);
        });
        $("#toggle3").click(function () {
            $("#toggle3div").toggle("drop", {direction:"right"}, 500);
        });
    });
