In HTML, the <select> tag creates a drop-down list of options for the user to choose from. Sometimes, you may want to hide certain options from the user for various reasons. This can be achieved using CSS by applying the display: none property to the <option> tag that you want to hide.

The disabled attribute can be set to keep a user from using the drop-down list until some other condition has been met (like selecting a checkbox, etc.). Then, a JavaScript can remove the disabled value, and make the drop-down list usable.

We use <select> and <option> elements to create a drop-down list and use the disabled attribute in <select> element to disable the drop-down list element. A disabled drop-down list is un-clickable and unusable. It is a boolean attribute.
