When the select box is clicked, a drop down list of options is displayed. The drop down list stays open until the user clicks outside or selects one of the options in the drop down list.

Is there a simple way of making the drop down list be displayed when user enters page? Like autofocus but better. Similar to how amazon displays it's menu automatically.

I understand that I could probably just make a ul dropdown list + javascript and etc, but was wondering whether there was a way of doing it with select using html or javascript.
