The mdb navigation bar seems to constantly change its height

Having an issue with the height of my mdb navbar in my Angular app. It randomly flips to a larger size when reloading the page, but returns to normal when I open the developer console in Chrome.

Two screenshots show the correct display and the incorrect increased height:

The navbar is in a separate Angular component added to the app.component.html like this:

<app-header></app-header>
<div class="d-flex p-2 justify-content-center">
  <router-outlet></router-outlet>
</div>

The header structure resembles the example provided by mdb

<mdb-navbar SideClass="navbar navbar-expand-lg navbar-dark indigo" [containerInside]="false">
  <mdb-navbar-brand>
    <a class="navbar-brand" [routerLink]="'/dashboard'">Admin Console</a>
  </mdb-navbar-brand>
  <links>
    <ul class="navbar-nav mr-auto">
      <li class="nav-item" routerLinkActive="active">
        <a class="nav-link waves-light" mdbWavesEffect [routerLink]="'/dashboard'">Dashboard</a>
      </li>
      <li class="nav-item" routerLinkActive="active">
        <a class="nav-link waves-light" mdbWavesEffect [routerLink]="'/todo'">Users</a>
      </li>
      <li class="nav-item" routerLinkActive="active">
        <a class="nav-link waves-light" mdbWavesEffect [routerLink]="'/todo'"">>A</a>
      </li>
      <li class="nav-item"> routerLinkActive="active">
        <a class="nav-link waves-light" mdbWavesEffect [routerLink]="/todo">B</a>
      </li>
    </ul>
    <span class="fill-remaining-space"></span>
    <ul class="navbar-nav ml-auto">
      <li *ngIf=!authService.isLoggedIn class="nav-item">
        <a class="nav-link waves-light" mdbWavesEffect [routerLink]="'/sign-in'">Login</a>
      </li>
      <li *ngIf=authService.isLoggedIn class="nav-item">
        &$lt;a class="nav-link waves-light" mdbWavesEffect (click)="this.authService.signOut()">Logout</a>
      </li>
    </ul>
  </links>

I attempted adding sticky-top as Sideclass to improve behavior when fixed content resides inside the router-outlet. However, the issue resurfaces when dynamic content like a table is loaded into the router-outlet as shown here:

Any suggestions on how to prevent the navbar from resizing? Thank you!

Answer №1

It appears there is a glitch in the component, but I have discovered a workaround. It seems that the div injected into the nav element has a style attribute used to control the height when the drop-down is active. The intended behavior is for the height to only increase when the drop-down is active, but in my case, it was increasing sporadically. To address this, I utilized the following CSS code to limit the max-height of the navbar when it is not in drop-down mode:

:host ::ng-deep mdb-navbar nav div :not(.show) {
    max-height: 40px !important;
}
