How to avoid selecting the default value in a <select> dropdown in Blazor?

November 20, 2024

I have a dropdown with a default value By default the first option is selected automatically but I want to ensure that users actively select a value instead of using the default

    <select @bind="SelectedValue">
      <option value="Option1">Option 1</option>
    <option value="Option2">Option 2</option>
    </select>

<p>Selected Value: @SelectedValue</p>

@code {
    private string SelectedValue = "";
}

>Solution :

<select @bind="SelectedValue">
    <option value="" disabled selected>Please select an option</option>
    <option value="Option1">Option 1</option>
    <option value="Option2">Option 2</option>
</select>

<p>Selected Value: @SelectedValue</p>

@code {
    private string SelectedValue = "";
}

The is used as a placeholder that appears as the default selection. It has an empty value attribute making it an invalid choice
