Here is my problem: In Laravel 6, i have a required element with the current options let say a, b, c:
<select class="form-control" name="mySelect" required> <option value="a">a</option> <option value="b">b</option> <option value="c">c</option> </select>
However, say d was a valid option previously and was saved to my back-end database. So now when I load my page, I'm setting mySelect to what is stored in the database but the select element is empty because d isn't an option anymore.
How can I make it so my select element as Invalid if it has a value that is not a valid option?
