How To Hide The Select Arrow On Firefox.md

This is no longer a bug. I'm keeping the gist for historical reasons, as it helped to get it fixed. Make sure to read the notes by the end of the post.

How to remove hide the select arrow in Firefox using -moz-appearance:none;

TL;DR (or, the fix)

1. Set -moz-appearance to none. This will "reset" the styling of the element;
2. Set text-indent to 0.01px. This will "push" the text a tiny bit^[1] to the right;
3. Set text-overflow to '' (an empty string). This will change anything that extends beyond the element's width to... nothing - and this includes the infamous arrow!

Continue reading for the full lowdown.

Background

I was experimenting on custom styling the <select> elements of a form I was building. One of the things I tried implementing was truncating the text with an ellipsis in case it extended beyond the <select>'s width. It didn't look consistent through browsers, but I discovered something nice.

The bug

Firefox <select> with appearance attribute set to none (Ubuntu):

Chrome <select> with appearance attribute set to none (Ubuntu):

As this 2011 bug report states, there is an issue regarding Firefox's -moz-appearance and <select> elements: it was supposed to ditch the <select>'s arrow (like Chrome's implementation) but it simply doesn't. People were raging about the subject all over the internetz.

Final considerations

• Firefox doesn't remove the arrow, it hides it. You will have some white space on the right^[2] (same width of the now-hidden arrow);
• Chrome removes the arrow by default with -webkit-appearance:none; instead of hiding. No white space on the right;
• Chrome doesn't support the text-overflow:''. No evenly-cut text;
• Your best bet is to set some padding-right in order to provide right space for your styled version of the arrow. Just keep in mind that Firefox will take the ghost arrow width into account;
• Turns out that Windows doesn't require the -moz-appearance: none; declaration at all. Tested on 8;
• Firefox for Android needs the whole width of the arrow as text-indent. It means you need to set it to at least 5px, but take care since Firefox seems to double the text-indent value on <select> elements.
• Zooming out (ctrl mousewheeldown, ctrl -, etc) reveals^[3] the default arrow. No big deal;
• The appearance attribute is not well supported through browsers, so take this workaround with a grain of salt when developing your crossbrowser solution.

Support

Tested on latest versions of Ubuntu, Windows, Mac and Android.

Notes

Edit 4: Mozilla released Firefox v35 and, indeed, the bug is patched. https://developer.mozilla.org/en-US/Firefox/Releases/35

Edit 3: Mozilla addressed the issue! Target milestone is v35. Yay!

Edit 2: Todd Parker from Filament Group tweeted about a CSS only alternative that works pretty much everywhere. You can check it here.

Edit: this trick stopped working as of Firefox 30 realeased in 2014-06-10. Join the comments section to help finding an alternative, and please upvote the bug on Bugzilla for a definitive fix. If you now have double arrows on Firefox, this might solve your issue.

Don't use any other value of -moz-appearance as the styles inherited are not customisable.

@iamalfonse: I was able to sort of emulate border and padding in @keska's solution by using inset box-shadow for border and color: transparent with an offset text-shadow for padding. See: http://jsfiddle.net/sstur/2EZ9f/

@anupjon's solution worked for me.

@joaocunha - Just used your URL prefix method to hide my custom arrow in FF33. Thanks a ton.

This issue is quite annoying, tested a couple hacks from here and there, but @anupjon's solution works for me as well in Win 7, FF32.
However I haven't figured out to make it appear as a working cursor, "cursor: pointer;" doesn't seems to work with "pointer-events: none;". If anyone figured that out let me know :)

@joaocunha's third solution worked for me. Thank you!

This solution is elegant ;)

@-moz-document url-prefix() {
 select {
    overflow:hidden; /* optional */
    width: 120%;
 }
}

Short option labels (like numbers 1, 2, 3...) were causing the select arrow to peak out with width: 120% for me.
This seems to be more flexible:

@-moz-document url-prefix() {
 select {
   width: calc(100% + 16px);
 }
}

-moz-appearance: none; will support select elements in Firefox 35. That version comes out in January, and the Developer Edition has this feature now. Here's the Bugzilla ticket.

Edit: Whoops, just realized that the content at the top of the gist already explains that. Sorry for the extra comment!

Well, well!!!

The solution is very near of us... maybe in next Firefox release!!!
I made a workaround in the meantime:

Tested on Chrome 39, Safari 8 and FF 33 and FF 35 Developer Edition

Solution does not work if border: 0.
FF 33.1, Win7

A modified combination of @Martskin and @iLenElFuerte comment worked best for me, as overflow: hidden would break the layout for me:

@-moz-document url-prefix() {
   select{
        overflow: -moz-hidden-unscrollable;
        width: calc(100% + 16px);
    }
}

Use this codepen if you want to support firefox: http://codepen.io/gijs/pen/MYKreR
It uses pseudo child's to hide the down arrows. (firefox, ie10+, chrome, safari, etc..)

@anupjon FTW!!! Thanks for posting that solution it worked for me. Just need to adjust to account for screen breaks.

UPDATE - If you are following @anupjon 's solution, just be aware of the float: left; set on the "selectwrap" div - It will cause a slight issue with various breakpoints.

Too much words...

It should be formatted like this for faster and better reading!

-- very long explanation goes after all of the primary codes --

anyway, thank you for sharing... 😊

Great solution @gijsroge , i like how you just used a character to create the arrow, there is similar tutorial on how to do this here (also works in firefox) https://fabriceleven.com/design/clever-way-to-change-the-drop-down-selector-arrow-icon/
