What is true of it
Dm(maj7) is D, F, A and C♯ — 1, b3, 5 and 7 counted from D.
On an instrument that cannot reach all 4, the 5 goes first, in that order.
The easiest of the 3 fingerings below is 7554: 4 fingers, held at the 4th fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
Where its notes are on the neck
The brass dots are D, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
