HTML <optgroup> Tag
The optgroup tag generates a group of options within a <select> control's dropdown list of values.
A sequence of <option> tags define the dropdown values, which are then grouped using the <optgroup> tag.
The <optgroup> label value will appear as a grey heading above the grouped items in the choose control. The <optgroup> element is another popular name for this tag.
