Explanation:
In the above code, we create a simple HTML page with a dropdown select element using MUI (Material UI) style. The select element is wrapped inside a div with the “mui-select” class. CSS is applied to style the select element, including a custom dropdown arrow symbol.
To set a default value for the select element, we use JavaScript. The script section at the end of the code retrieves the select element by its ID (“mySelect”) and sets its value to “option2”, which will make “Option 2” selected by default.
You can replace “option2” with any other value from the available options to set a different default value.
