[accordion] How to temporarily disable some sections?


I have a test accordion like this:
<div id="test">
    <div class="accordion_item">
        <h3>blah</h3>
        <div>aaaaaaaaaaaaaaaaaaaaaaa</div>
    </div>
    <div class="accordion_item">
        <h3>blah</h3>
        <div>aaaaaaaaaaaaaaaaaaaaaaa</div>
    </div>
    <div class="accordion_item">
        <h3>blah</h3>
        <div>aaaaaaaaaaaaaaaaaaaaaaa</div>
    </div>
</div>
Each section will be a form, and I want the user to be able to:
1. Go back to any previous section/form to edit
2. MUST submit the form he/she is filling first to go to the next one
So I need a way to temporarily prevent some section to expand even if
the user clicks on it. Is there anyway to do this?
Thanks all
