The select dropdown default choice is not appearing as expected

My template is not showing the default select option that I have set for one select element.

I attempted to achieve this with the following code:

<div class="select">

    <select (change)="calculaMes(mesEscolhido)" [(ngModel)]="mesEscolhido" name="selectMesEscolhido"
    class="select-text">
       <option class="dropdown-item" disabled selected value>Test</option>
       <option [hidden]="datasComMovimentacoes[x].data == mesEscolhido" *ngFor="let mes of datasComMovimentacoes;let x = index"
       class="dropdown-item">{{mes.data}}</option>
    </select>

   <span class="select-highlight"></span>
   <span class="select-bar"></span>

</div>

I don't think the issue lies in my CSS, but here it is:

 .select {
    font-family:
      'Roboto','Helvetica','Arial',sans-serif;
      position: relative;
      width: 100%;
      margin-top: 5%;
      font-size: 18px;
      color: #757575!important;
  }

  .select-text {
      margin-top: 10%;
      position: relative;
      font-family: inherit;
      background-color: transparent;
      color: #757575!important;
      width: 100%;
      font-size: 18px;
      border-radius: 0;
      border: none;
      border-bottom: 1px solid rgba(0,0,0, 0.12);
  }

  /* Remove focus */
  .select-text:focus {
      outline: none;
      color: #757575!important;
      border-bottom: 1px solid rgba(0,0,0, 0);
  }

      /* Use custom arrow */
  .select .select-text {
      appearance: none;
      color: #757575!important;
      -webkit-appearance:none
  }

This is what my template looks like currently:

Answer №1

To ensure that the default option is selected, make sure that the value attribute of the option tag matches the default value assigned to the selectedOption property in your Component. If the selectedOption property is not initialized, its default value will be undefined. Therefore, the value attribute of the option tag should also be set as undefined in this scenario.

...
<option class="dropdown-item" disabled selected value="undefined">Select an Option</option>
...

Take a look at this Sample StackBlitz for more information.

Answer №2

For anyone curious, this information is currently unavailable due to personal reasons. I have made some adjustments and now everything appears as it should. The reason behind the initial issue remains unclear to me.
