Trigger click on select box on hover

Solution 1:

I finally got this to work! You need Chosen; as others have pointed out, you can't do this with a normal select because there are no events available to use. But this will pop open the menu when you mouseover the select and close it when you mouseout, which is the exact effect I wanted.

HTML:

<select id="dropdown" data-placeholder="Choose&hellip;">
    <option value="one">Option 1</option>
    <option value="two">Option 2</option>
    <option value="three">Option 3</option>
</select>

JS:

$("#dropdown").chosen().next(".chzn-container").hover(
    function(){
        $("#dropdown").trigger("liszt:open");
    },
    function(){
        $(this).trigger("click");
    }
);

$("#dropdown").trigger("liszt:open"); is what opens the menu. There is no equivalent liszt:close event to trigger when you want to close it (as far as I know), but triggering a click on it instead has the same effect.

Solution 2:

It's been a while but there is a solution I don't see here, using hover to change the length of select :

$('select').hover(function() {

  $(this).attr('size', $('option').length);
}, function() {

  $(this).attr('size', 1);
});

And here's a pen where it's a bit more than the bare necessity and has some styling :
