How do I modify HTML select box using CSS / jquery

I'm trying to "cheat" the design of a select box to act as an inline tab/widget.

After done some research, I know it's hard to modify by CSS. But I think it's probably manageable.

So, based on the codepen below, when I click the option, the text will turn white. Only once I click some white space, the text become black. Why is that and how to fix it?

Secondly, how to remove the right side arrow bar thing? I run this CSS on the staging site, chrome doesn't show the arrow bar, but mozilla got.

What I have tried:

- I thought maybe it's because of selection thing, so I tried css below but nothing happened

::selection {color:#000 !important;}

- I also tried select option:active, select option:focus but still the same.

I'm sorry to say, that what you are looking to do is not achievable. Color and background color may not be set on a select option. However, you may set the background-image. The code below demonstrates setting the background image through the use of JQuery (and resetting the background of the un-selected option). It also hides the right side scroll bar through CSS overflow:hidden

<!DOCTYPE html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript">
	$(document).ready(function () {
			$('#mySelectList').change(function (){
			var $option = $(this).find('option:selected');			
			$option.css('color','#00000');  // <-- this is not permitted, can't set color or background on an option
			$option.css('background-image','linear-gradient(blue, gray)');
			// reset all			
			var $unoption = $(this).find('option:not(:selected)');			
			$unoption.css('background-image','none');
		});
	});
</script>
<style>
select {
	width: 100%;
	padding: 0;
	border: none;
  background-image: none;
	font-size: 16px;
	color: #868686;
	overflow: hidden;
}

select option {
		display: inline;
		float: left;
		margin-right: 128px;
}

select option:hover {
		cursor: pointer;
}

select option:checked {
		font-weight: 600;
}

</style>
<html>
<body>
 
<select id="mySelectList" multiple="multiple">
  <option value="">Latest</option>
  <option value="52">New</option>
  <option value="53">Pre-Owned</option>
  <option value="115">Unworn</option>
</select>
