Answer 1

From the documentation You can use data-collapsed=false

<div data-role="collapsible-set">

    <div data-role="collapsible" data-collapsed="false">
    <h3>Section 1</h3>
    <p>I'm the collapsible set content for section 1.</p>
    </div>

    <div data-role="collapsible">
    <h3>Section 2</h3>
    <p>I'm the collapsible set content for section 2.</p>
    </div>
</div>
