Toggle a Div container height

I am working on a button on which the toggle applies and the div height increases and decreases. So what i am trying to do is that on a button lets say on #about click the #aboutsubmenu shows and the height of #maincontainer increases and on same click if if it's open it closes. Here is what i am trying to do

$(document).ready(function() {
    $('#aboutsubmenu').hide();
    var opened;
    var opened2;
    $('#about').click(function() {
        opened = "no";
        if (opened == "no") {
            $('#aboutsubmenu').show();
            $('#maincontainer').css('height', '387px');
            opened = "yes";
        }
        else if (opened == "yes") {

        }
    });
});

I am totally confused here. Can you help me out.

Try this, Initialize your variable outside event handler

var opened = "no"; //
var opened2;
$('#about').click(function () {
    if (opened == "no") {
        $('#aboutsubmenu').show();
        $('#maincontainer').css('height', '387px');
        opened = "yes";
    } else if (opened == "yes") {
        $('#aboutsubmenu').hide();
        $('#maincontainer').css('height', '100px');
        opened = "no";
    }
});

Try this code:

$(document).ready(function () {
    $('#aboutsubmenu').hide();
    var opened = false;
    $('#about').click(function () {
        $('#aboutsubmenu').toggle(); // Toggle visibility
        $('#maincontainer').height(opened ? 387 : 100);
        opened = !opened;
    });
});

What you did wrong:

opened = "no";

that code at the start of the function makes it alwasy open.
