当 select 选择一个选项时，项目符号点出现在多 select 下拉框下方

Question

我正在构建一个 angular（7 是版本）页面，其中包含我正在使用的多个 select 下拉菜单 ng-multiselect-dropdown. Please see the below picture - 当我单击下拉菜单并尝试select 或 unselect 一个选项，然后这些蓝点出现（仅当 selecting 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：我对 multi-select-dropdown 样式做了一些自定义，尝试删除它们，但这并没有解决这个问题。

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

css

.multiselect-dropdown .dropdown-btn {
    display: inline-block;
    border: 1px solid #ccc !important;
    border-radius: 4px;
    box-shadow: none;
    color: #333;
    width: 100%;
    padding: 6px 14px;
    margin-bottom: 0;
    font-weight: 400;
    line-height: 1.52857143;
    text-align: left;
    vertical-align: middle;
    cursor: pointer;
    background-image: none;
}

.multiselect-dropdown:focus {
    outline: 0px !important;
    outline-style: none !important;
}

.multiselect-dropdown .dropdown-btn span.ng-star-inserted { padding-right: 14px; }

.multiselect-dropdown .dropdown-btn .dropdown-down {
    display: inline-block;
    top: 5px;
    width: 0;
    height: 0;
    border-top: 5px solid #aaa;
    border-left: 5px solid transparent;
    border-right: 5px solid transparent;

}

.multiselect-dropdown .dropdown-btn .dropdown-up {
    /*display: inline-block;*/
    width: 0;
    height: 0;
    border-bottom: 5px solid #aaa;
    border-left: 5px solid transparent;
    border-right: 5px solid transparent;

}

.multiselect-dropdown .dropdown-btn .selected-item {
    background: #111 !important;
    border: 1px solid #111 !important;
    border-radius: 3px !important;
    color: #fff;
    float: left;
    margin: 0 1px 1px 0 !important;
    padding: 0 5px;
}

.multiselect-dropdown .dropdown-btn .selected-item:hover {
    background-color: #00a7ea !important;
    border-color: transparent !important;
}

.multiselect-item-checkbox input[type="checkbox"] + div:before {
    box-sizing: content-box;
    content: '';
    color: #111 !important;
    position: absolute;
    top: 50%;
    left: 0;
    width: 14px;
    height: 14px;
    margin-top: -9px;
    border: 2px solid #111 !important;
    text-align: center;
    transition: all .4s ease;
}

.multiselect-item-checkbox input[type="checkbox"]:checked + div:before {
    -webkit-animation: .2s ease-in borderscale;
    animation: .2s ease-in borderscale;
    background: #111 !important;
}

通过向 ng-multiselect-dropdown 添加 class="multiselect-dropdown" 然后覆盖 'focus' 样式解决了上述问题。

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

}
