The third voice from the top lowered an octave. The dropped voice becomes the bass, which is why a string is skipped.
Gm11 is G, Bb, D, F, A and C — Gm9 with the eleventh added on top.
It sounds spacious and slightly unresolved. The eleventh is a whole step above the minor third, so unlike its major counterpart it fits without a fight.

| G | Bb | D | F | A | C |
|---|---|---|---|---|---|
| 1 | ♭3 | 5 | ♭7 | 9 | 11 |
Pre-dominant or minor tonic — it hangs rather than moves.
Also written Gmin11, G-11 or G minor 11. The same chord either way; which spelling you meet depends on who wrote the chart.
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
Gm11 has 10 of them, on strings 5-3-2-1 and strings 6-4-3-2, from open position up to the 13th — every inversion the chord has: G in the bass, Bb in the bass, F in the bass and C in the bass. The one to learn first is the Bb shape at the nut.
5 of them sit on strings 5-3-2-1, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with xx5566 — no barre and low, at the 5th fret. None of the shapes for Gm11 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 7 of the 8 need a barre. Together they cover the neck from the 1st fret to the 15th.

The same notes rebuilt from scratch give 8 shell, 15 drop 2, 25 rootless and 3 open string voicings, each on its own page.
Tensions. A shell of Gm11, root, third and seventh, leaves a string free, and the tones that belong over it are the 13 (E).
How you get to it. The turn that lands on Gm11 is Am7♭5 to D7♭9: the ii and the V of G minor, which is where a minor tonic is usually arrived at rather than simply begun on.
In which keys. Every note of Gm11 belongs to D minor (the iv, the subdominant), F major (the ii, the supertonic), G minor (the i, the tonic) and Bb major (the vi, the submediant).
Every note of Gm11 is in G dorian and G natural minor.
Change one note of Gm11 and you have Gm9 (drop the fourth), GmMaj11 (the flat seventh becomes a major seventh) or G11 (drop the minor third).
Gm11 is a minor chord — root, minor third, fifth. Minor chords on every root.
