Keep a jQuery dialog in a div

Question

I am trying to create a number of jQuery dialogs but I would like to constrain their positions to inside a parent div. I am using the following code to create them (on a side note the oppacity option is not working either...):

var d= $('<div title="Title goes here"></div>').dialog({
            autoOpen: true,
            closeOnEscape: false,
            draggable: true,
            resizable: false,
            width: dx,
            height: dy
        });

        d.draggable('option', 'containment', 'parent');
        d.draggable('option', 'opacity', 0.45);

        $('#controlContent').append(d.parent());

Answer 1

I have found a way to do it. This is now my method for creating a dialog:

    var d = $('<div title="Title"></div>').dialog({
        autoOpen: true,
        closeOnEscape: false,
        resizable: false,
        width: 100,
        height: 100
    });

    d.parent().find('a').find('span').attr('class', 'ui-icon ui-icon-minus');
    d.parent().draggable({
        containment: '#controlContent',
        opacity: 0.70
    });

    $('#controlContent').append(d.parent());
