尝试在选择部分插入SVG图像，如下所示：In FIGMA
不明白我的代码中有什么错误。

.contacts__select {
  margin: 0;
  margin-top: 95px;
  margin-left: 64px;
  position: relative;
  height: 50px;
  width: 450px;
  background-color: #D6E7D2;
  border: none;
  box-shadow: 0px 4px 4px 0px #00000040;
  align-self: flex-start;

  -webkit-appearance: none;
  -moz-appearance: none;
  -ms-appearance: none;
  appearance: none;

  font-family: 'Inter';
  color: #717171;
  font-size: 20px;
  font-weight: 400;
  line-height: 40px;
  letter-spacing: 0.05em;
  text-align: left;
}

.contacts__select::after {
  position: absolute;
  content: '';
  background-image: url('./assets/img/svg/accordion_btn.svg');
  bottom: 0;
  right: 0;
}

我尝试了不同的组合，如果左/右上/下。无论如何不工作。my version

你可以用CSS Flex来实现，它非常强大。
我们所要做的就是将标题和SVG（子对象）放在一个显示Flex（父对象）中，然后告诉子对象居中对齐，并将它们彼此隔开

.dropdown {
    display: flex;
    justify-content: space-between;
    align-items: center;

    background-color: #d6e7d2;
    box-shadow: 0px 4px 4px 0px #00000040;
    height: 50px;
    padding: 0 16px;
}

.dropdown__title {
    font-family: 'Inter';
        color: #717171;
    font-size: 20px;
    font-weight: 400;
}

.dropdown__icon {
  width: 24px;
  height: 24px;
}

<div class="dropdown">
    <span class="dropdown__title">City</span>
    <span class="dropdown__icon">
        <img src="/assets/img/svg/accordion_btn.svg" alt="icon">
    </span>
</div>
