custom scrollbar

jScrollPane .. I've heard bad things about it.

fleXscroll .. I've used it, it's nice, but it's not free.

jsScrolling .. I haven't used it, but it looks nice and it's free.

Improved email validation, plus multiple emails validation

jQuery validation plugin .. was causing ff2 to choke. It also didn't have a multiple-email validator .. or a split-up phone validator -- although on that last one, I highly advise you push back - a phone # field should just be ONE INPUT.

The *real* way to disable text selection

I was recently asked by UX to make the text of my fancy custom dropdown selects unselectable. A lot of silly scripts out there that disable text selection are application-unfriendly. They go beyond unselectable and make the element totally non-interactive. But I still want the dropdown to work when you click it. Solution = css for the "good" browsers, and javascript for internet explorer.

CSS

.unselectable{
    -moz-user-select: none;
    -webkit-user-select: none;
}

JS

if(document.attachEvent){
    function returnFalseFn(){
        return false;
    }
    jQuery('.unselectable').each(function(){
        this.attachEvent('onselectstart', returnFalseFn);
    });
}
