I thought this would be a simple hack, but I've now been searching for hours and can't seen to find the right search term. I want to have an ordinary multiple select box (<select multiple="multiple">
) except I don't want the user to have to hold down the control key to make multiple selections.
In other words, I want a left click to toggle the <option>
element that's under the cursor without changing any of the others. In other other words, I want something that looks like a combo list box but behaves like a group of check boxes.
Can anybody suggest a simple way to do this in Javascript? Thanks.

You basically need to override the mousedown
event for each <option>
and toggle the selected
property there.
$('option').mousedown(function(e) {
e.preventDefault();
$(this).prop('selected', !$(this).prop('selected'));
return false;
});
For simplicity, I've given 'option' as the selector above. You can fine tune it to match <option>s
under specific <select>
element(s). For ex: $('#mymultiselect option')
