How to automatically expand html select element in javascript

Question

I have a (hidden) html select object in my menu attached to a menu button link, so that clicking the link shows the list so you can pick from it.

When you click the button, it calls some javascript to show the <select>. Clicking away from the <select> hides the list. What I really want is to make the <select> appear fully expanded, as if you had clicked on the "down" arrow, but I can't get this working. I've tried lots of different approaches, but can't make any headway. What I'm doing currently is this:

<li>
    <a href="javascript:showlist();"><img src="/images/icons/add.png"/>Add favourite</a>
    <select id="list" style="display:none; onblur="javascript:cancellist()">
    </select>
</li>

// in code
function showlist() {
    //using prototype not jQuery
    $('list').show();  // shows the select list
    $('list').focus(); // sets focus so that when you click away it calles onblur()
}

• I've tried calling $('list').click().
• I've tried setting onfocus="this.click()" But in both cases I'm getting

Uncaught TypeError: Object # has no method 'click'

which is peculiar as link text says that it supports the standard functions.

I've tried setting the .size = .length which works, but doesn't have the same appearance (as when you click to open the element, it floats over the rest of the page.)

Does anyone have any suggestions?

You have a syntax error. It should be:

$('#list').click();

You forgot the #
