选择选项时，项目符号点显示在多选下拉列表框下方

Question

我正在构建一个angular（7版本）页面，该页面具有我正在使用的ng-multiselect-dropdown的多选下拉列表。请参见下图-，当我单击下拉列表并尝试选择或取消选择一个选项时，这些蓝点就会出现（仅在选择或取消选择时）。知道如何摆脱它们吗？如果我检查该元素，它不会提供任何线索。  注意：我已经对多选下拉列表样式进行了一些自定义，尝试删除它们，但这并不能解决此问题。

 <ng-multiselect-dropdown name="selectedOptions"
           tabindex="3"
           [data]="dropdownList"
           [(ngModel)]="selectedOptions"
           [settings]="dropdownSettings"
           (onSelect)="onItemSelect($event)"
           (onSelectAll)="onSelectAll($event)">
</ng-multiselect-dropdown>

通过在ng-multiselect-dropdown中添加class =“ multiselect-dropdown”并覆盖“ focus”样式来解决上述问题。

.multiselect-dropdown:focus {
outline: 0px !important;
outline: -webkit-focus-ring-color auto 1px;
outline: 0px solid #111;

}
