ng使用深层链接的bootstrap下拉菜单样式

Question

我想设置ng bootstrap下拉菜单的样式，基本上将其宽度更改为auto。但是我不知道如何使用/ deep /链接来定位它。

我想定位ngbDropdownMenu。

这是它的HTML：

 <div ngbDropdown class="d-inline-block">
      <button class="btn btn-custom" id="columnToggle" ngbDropdownToggle ngbTooltip="Filter">
        <fa-icon [icon]="faColumns" title="Select to Show/Hide Columns"></fa-icon>
      </button>
      <div ngbDropdownMenu aria-labelledby="columnToggle">
        <button class="dropdown-item" *ngFor="let column of columnList">
          <label>
            <input type="checkbox" [checked]="column.selected" (change)="changeSelectedColumns.emit(column)" [disabled]="column.disabled"
            /> {{column.header}}
          </label>
        </button>
      </div>
    </div>

Answer 1

您可以将一个类添加到div nbgDropdownMenu

<div ngbDropdownMenu aria-labelledby="dropdownBasic1" class="custom">
     <button class="dropdown-item">Action - 1</button>
     <button class="dropdown-item">Another Action</button>
     <button class="dropdown-item">Something else is here</button>
</div>

.custom{
    background-color:Red;
    width:auto;
    padding:20px;
  }
