Use the `defaultvalue` or `value` props on instead of setting `selected` on . 25 September 2023 by thecoderscamp.com The correct way to set the default value for a select element in HTML is to use the defaultValue or value prop on the <select> tag instead of setting the selected attribute on the <option> tag. Example: Let’s say we have a select element with three options: <select defaultValue="option2"> <option value="option1">Option 1</option> <option value="option2">Option 2</option> <option value="option3">Option 3</option> </select> In the above example, we have set the defaultValue prop on the select element to “option2”. When the page loads, “Option 2” will be selected by default. Using the defaultValue or value prop ensures that the default value is properly maintained in the select element, even when the component re-renders.
