On the staff
On a bass staff, CmMaj7 is written C, E♭, G and B.
The staff shows the notes one after the other, then together. Written this way the chord is in close position, which means each note sits as near to the one below it as the spelling allows. A guitar almost never plays a chord in close position.
CmMaj7 under a hand
Strummed from the lowest string to the highest, this grip sounds E♭, B, E♭, G and C, which are the degrees ♭3 7 ♭3 5 1 rather than the 1 ♭3 5 7 of the written chord. The lowest note is the ♭3 rather than the root, so this grip is in first inversion, written CmMaj7/E♭. It has the same notes as the root-position grip, but with E♭ in the bass it sounds different. With E♭ in the bass and five strings sounding four notes, the ♭3 appears more than once.
Strummed from the lowest string to the highest, this grip sounds G, B, G, C and E♭, which are the degrees 5 7 5 1 ♭3 rather than the 1 ♭3 5 7 of the written chord. The lowest note is the 5 rather than the root, so this grip is in second inversion, written CmMaj7/G. It has the same notes as the root-position grip, but with G in the bass it sounds different. With G in the bass and five strings sounding four notes, the 5 appears more than once.
Strummed from the lowest string to the highest, this grip sounds B, G, C, E♭, G and C, which are the degrees 7 5 1 ♭3 5 1 rather than the 1 ♭3 5 7 of the written chord. The lowest note is the 7 rather than the root, so this grip is in third inversion, written CmMaj7/B. It has the same notes as the root-position grip, but with B in the bass it sounds different. With B in the bass and six strings sounding four notes, the 1 and 5 appear more than once.
Three shapes for CmMaj7 on 6-string bass: CmMaj7/E♭, CmMaj7/G and CmMaj7/B.
CmMaj7 has no root-position shape on 6-string bass, because there is no way to put the root below the other notes and still reach the whole chord. A chord with a note other than the root at the bottom is called an inversion, and every way of playing CmMaj7 here is one. That comes from how this instrument is tuned, not from the chord itself. When a grip sounds a note more than once, the fretting hand decides which note that is, not the harmony.
C, E♭, G and B on the whole neck
This diagram marks every C, E♭, G and B on the first fifteen frets of the 6-string bass.
Every grip above is a handful of the notes on this diagram, and none of them uses a note that is not shown here.
