<optgroup> HTML option group element
Baseline
Widely available
*
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
* Some parts of this feature may have varying levels of support.
The <optgroup> HTML element creates a grouping of options within a <select> element.
In customizable <select> elements, the <legend> element is allowed as a child of <optgroup>, to provide a label that is easy to target and style. This replaces any text set in the <optgroup> element's label attribute, and it has the same semantics.
Try it
<label for="dino-select">Choose a dinosaur:</label>
<select id="dino-select">
<optgroup label="Theropods">
<option>Tyrannosaurus</option>
<option>Velociraptor</option>
<option>Deinonychus</option>
</optgroup>
<optgroup label="Sauropods">
<option>Diplodocus</option>
<option>Saltasaurus</option>
<option>Apatosaurus</option>
</optgroup>
</select>
label {
display: block;
margin-bottom: 10px;
}
Note: Optgroup elements may not be nested.
Attributes
This element includes the global attributes.

If this Boolean attribute is set, none of the items in this option group is selectable. Often browsers grey out such control and it won't receive any browsing events, like mouse clicks or focus-related ones.
label-
The name of the group of options, which the browser can use when labeling the options in the user interface. This attribute is mandatory if this element is used.
Examples

<optgroup label="Group 3" disabled>
