You will have to put the album into a Playlist.
This can be a temporary if you wish. Then you can burn that Playlist to disc. Once done, you can delete the Playlist. It will not affect the songs.
"Playlist" is a specific term and iTunes has (apparently) been designed so that it can only burn CDs from "Playlists".
A playlist is simply a list of songs that you want to play (or think of) as one group, which means that in that respect, albums are "playlists". Each genre in iTunes is also "a playlist". But those "playlists" are not the same as the type that can be used to burn a CD.
So, to burn a CD, the songs have to be in the type of Playlist listed under the All Playlists heading, shown in the sidebar.
The word iTunes has two meanings as well:
- the computer programme that you have on your computer (except for those with a Mac running OS Catalina)
- the online store, where you can buy music etc. (The iTunes Store is available from within iTunes {the programme} or via the iTunes Store app on iPods, iPhones etc.)
To put one specific album into a Playlist, you can either use:
- a Regular Playlist - you simply drag the songs into the Playlist
- a Smart Playlist - (these have rules). To put the Chemical Brothers album We Are The Night into a Smart Playlist, the rules would look like the rules would look like the one shown below:
and the resulting Playlist, which is created for you according to the rules of the Playlist, looks like this:
No need to drag songs into a list.
I changed the view of this Playlist and confirmed that the songs are in the correct track order. You can re-arrange the order if you need to. Notice in the screenshot that Burn to Disc is no longer greyed out, but if we look in the Albums view, at the same album, Burn to Disc is still greyed out and not usable:
