How to play C#m11
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.
C#m11 has 8 of them, on strings 6-4-3-2 and strings 5-3-2-1, from the 2nd fret up to the 11th — every inversion the chord has: C# in the bass, E in the bass, B in the bass and F# in the bass. The one to learn first is the F# shape at the 2nd fret.
4 of them sit on strings 6-4-3-2, 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 x-x-11-11-12-12 — no barre. None of the shapes for C#m11 uses an open string, so every one of them is movable; the lowest sits at the 2nd fret. 6 of the 7 need a barre. Together they cover the neck from the 2nd fret to the 12th.
