<head> section of an HTML document contains metadata about the document, and as a minimum it must include a
<title> tag defining the document title.
Common causes for this issue are forgetting to define the
<title>, or duplicated
<head> sections where one of them does not include the title.
Here’s an example of a minimal HTML document including the title:
<!DOCTYPE html> <html> <head> <title>Don't panic! This is the title</title> </head> <body> <p></p> </body> </html>
Drop-down lists can be defined in HTML by using the
<select> tag, containing the different
<option> must have a name, which can be either contained between
</option>, or alternatively using the
<select name="size"> <option value="s">small</option> <option value="m" label="medium"></option> </select>
