How Can I Remove the Border from a Drop-Down List in CSS?

Removing Border from Drop-Down List in CSS

A common design concern is removing the border that appears around drop-down lists. While some styling options are available for the input field itself, it's not possible to directly modify the border of the drop-down box.

Custom CSS Not Working

Often, developers attempt to remove the border using CSS rules like the following:

select#xyz option {
  Border: none;
}

However, this approach doesn't work because the drop-down box is rendered by the operating system, not affected by custom CSS.

Alternative Solutions

If you desire more control over the appearance of your input fields, consider exploring JavaScript solutions.

Alternatively, if your goal is to remove the border from the input field, ensure you use the correct selector. Instead of targeting the option elements within the list, use the following code:

select#xyz {
    border: none;
}

This code will remove the border from the input field associated with the drop-down list, without affecting the drop-down box itself.
