contact form customisation Dropdown menu

Site URL: https://chloe-chow.squarespace.com/contact?noredirect

Hello, 
I have a question related to my contact form. I have customised the radio and check box along with my select / drop down field. 
Here is my website: https://chloe-chow.squarespace.com/contact?noredirect

I am trying to add back an arrow at the end of my select field however it's not working. Do you have an idea on how to do it ? I think I am using the wrong selector to add my arrow :after . Here is the code below :
 

// *** CUSTOMIZED OPTION DROP MENU 
/* Resetting the Option menu */
.form-wrapper select {
-webkit-appearance: none;
-moz-appearance: none;
  appearance: none;
  border: @line solid;//*//
  border-radius: 5px;
  padding: 1rem;
  width: 100%;  
}
/*Add an arrow*/
.sqs-block-form .field-list .option select:after {
content:'⇲';
color: red !important;
position: absolute;
display: block;
top: 55%;
transform: translateY(-50%);
right: 8%;

pointer-events: none;
}

// Option Menu when Focused
.form-wrapper select:focus, a:focus {
outline-width: 0px;
outline-style: solid;
  }

What do you think ? 

Thanks !!
 

I guess select doesn't support pseudo element (:after, :before)?

Try

.sqs-block-form .field-list select {
-webkit-appearance: none;
  -moz-appearance: none;
  background: transparent;
  background-image: url("data:image/svg+xml;utf8,<svg fill='black' height='24' viewBox='0 0 24 24' width='24' xmlns='http://www.w3.org/2000/svg'><path d='M7 10l5 5 5-5z'/><path d='M0 0h24v24H0z' fill='none'/></svg>");
  background-repeat: no-repeat;
  background-position-x: 100%;
  background-position-y: 5px;
  border: 1px solid #dfdfdf;
  border-radius: 2px;
  margin-right: 2rem;
  padding: 1rem;
  padding-right: 2rem;
}

Hey @tuanphan !! Thanks for your reply, I just saw it this morning.
