Select2 選擇下拉式選單：清除與文字重疊的圖標

Question

我遇到一個問題，文字在選擇選單中懸停的 X「清除」按鈕下重疊。在右側添加填充並不是解決方案，因為它將圖標推到框外。我正在使用此處找到的 Select2 JS 庫 https://select2.org/ 和 Bootstrap 5

$("#search_bar").select2({
  theme: 'bootstrap-5',
  placeholder: "Some text",
  allowClear: true
});

<div class="">
  <select id="search_bar" class="form-select w-25">
    <option value="1">
      This is a long option string
    </option>
    <option value="2">
      This is another long option string
    </option>
  </select>
</div>

Answer 1

在下面加入 CSS。

.select2-selection__clear {
    位置：絕對！重要；
    右：2px！重要；
}

Answer 2

依照此處的文檔操作 Select2 文檔。您可以使用 width: 'style' 和標籤 <select> 中的內聯樣式來擴展 select2 寬度。這裡我將select的寬度設定為200px

#然後，透過查看 select2 的 DOM 結構（使用 Chrome Devtool），我發現我們可以透過新增以下 CSS 來讓 X 按鈕不與文字重疊：

.select2-selection.select2-selection--single {
  padding-right: 50px !important;
}

$("#search_bar").select2({
  theme: 'bootstrap-5',
  placeholder: "Some text",
  allowClear: 真,
  width: 'style'
});

.select2-selection.select2-selection--single {
  padding-right: 50px !important;
}

      This is a long option string
    
    
      This is another long option string
