What is the name of the menu that displays details on Android?

If you are using Phonegap, then I recommend using JQuery Mobile as it has a feature called collapsible and its way of using it can be found here .

<div data-role="collapsible">
    <h4>Isso vai aparecer no botão</h4>
    <button>opção1</button>
<button>opção2</button>
</div>
