I'm having some trouble getting my HTML menu within the header tag to hover correctly in Angular. Can someone please provide

https://i.sstatic.net/SK6Dw.png

My Angular application's CSS is causing the menu to not hover over all controls in the component.

CSS

    nav {
          background-color: #4D678D;
        }      
        nav ul {
          padding: 0;
          margin: 0;
          list-style: none;
          position: relative;
        }
        nav ul li {
          display: inline-block;
          background-color: #4D678D;
        }
        nav a {
          display: block;
          padding: 0 15px;
          color: #fff;
          line-height: 50px;
          font-size: 14px !important;
          text-decoration: none;
        }
        /* Hide Dropdown by Default*/
        nav ul ul {
          display: none;
          position: absolute;
          top: 50px;
        }  
        /* hover */
        nav a:hover {
          background-color: #051731;
        }
        /* Display Dropdown on Hover */
        nav ul li:hover>ul {
          display: inherit;
        }

Answer №1

If you want to display the dropdown above all elements, one way to achieve this is by using the CSS property z-index. By applying a higher z-index than the other elements, you can ensure that the dropdown appears on top. One approach is to add the CSS class display-over-all and set the z-index with the use of !important. Hopefully, implementing this solution resolves your issue!

CSS

.display-over-all {
  z-index: 3000 !important;
}

HTML

    ...
    <a
      href=""
      [routerLink]="item.link"
      *ngIf="item.children && item.children.length > 0"
      >{{ item.label }}</a
    >
    <ul class="display-over-all"> <!-- CSS class added here -->
      <li *ngFor="let child of item.children">
         ...
