HTML Select option disabled selected is one of the fundamental HTML attributes used in web development. It is a feature that allows developers to add an option in a drop-down list, which cannot be selected by the users. Developers usually use this feature to create user interface designs that need to pre-select options for the user but need to disable other options that are not applicable.
In this article, we will be discussing HTML Select option disabled selected attribute, its applications, and various examples.
What Is HTML Select Option Disabled Selected?
HTML Select option disabled selected is a dual attribute in HTML. It combines two features in one attribute, which are disabled and selected. When you set this attribute in an option element, it ensures that the option is disabled and selected but will not be editable by the user. The user cannot select or change the option, but the option is used to show pre-selected values in the list.
The disabled option flag prevents users from submitting invalid data while the selected option ensures that the intended values are pre-selected. Often, developers use disabled selected options to provide users with a default option while disabling other options in the drop-down list.
Syntax for HTML Select Option Disabled Selected attribute
Below is the syntax for the HTML Select option disabled selected attribute:
As you can see, this syntax provides the disabled selected option. It provides a pre-selected value, and it disabled the option for further selection.
With the syntax above, you can quickly create a dropdown list with the first value disabled (not selectable by users) but pre-selected.
Uses of HTML Select option Disabled Selected?
HTML Select Option Disabled Selected attribute is useful when you want to show a specific value or option in a drop-down list, but you want to prevent users from selecting or changing the selected option. Here are some of the uses of this attribute:
-
Pre-selected value: HTML Select Option Disabled Selected is used to pre-select a certain value for the user.

Examples of HTML Select Option Disabled Selected
Here are some examples of HTML Select Option Disabled Selected:
Example #1: Pre-selected Value
This example shows how to pre-select an option in a drop-down list and disable the same option.
As you can see, the first option is disabled and also selected. When the user opens the drop-down, the first option is already pre-selected and cannot be changed. It is used to give the user default options or values.
Example #2: Skipping Invalid Inputs
This example shows how to skip invalid inputs by restricting choices in the input field.
In this example, options 2007 and 2008 are disabled because they are not currently available. The earlier years are available. The use of disabled options here ensures that users select only valid input and prevents the possibility of an application error.
Example #3: Ensuring Compatibility of User Actions
This example shows how to ensure compatibility between user actions and subsequent options.
In this example, the Luxury option is the only one available. The available options depend on the user's previous selection. In this case, the only option available depends on the class of vehicle selected.
