How to Disable a Select Dropdown in Angular?

To disable a select dropdown in Angular you can bind the disabled property of the dropdown with a boolean flag(eg. isDisabled). If the value of this flag is true, the dropdown will become disabled otherwise, if it is false, the dropdown will remain enabled.

This is how you can bind the isDisabled flag to your select dropdown in your template file:

<select [disabled]="isDisabled">
    <option value="op1">Option1</option>
    <option value="op2">Option2</option>
    <option value="op3">Option3</option>
    <option value="op4">Option4</option>
</select>

Next, you have to declare the isDisabled flag inside your component’s ts file and set its value to true to make the dropdown disabled:

isDisabled: boolean = true;  
// Makes dropdown disabled

Note: You can make the dropdown enabled or disabled dynamically by changing the value of the isDisabled flag based on some logic inside your ts file.
