Eb to G is a major third (4 semitones), G to Bb is a minor third (3 semitones), Bb to Db is a minor third (3 semitones), Db to F is a major third (4 semitones), F to Ab is a minor third (3 semitones). All six notes stacked in thirds, 1 3 5 b7 9 11. The eleventh, Ab, sits a minor ninth above the third G and clashes with it, so in practice the third is left out: Eb Bb Db F Ab is how Eb11 is usually played, the same notes as Eb9sus4. Leave out the fifth as well and the engine hears Db/Eb instead (Eb Db F Ab), so the guitar shapes here keep Bb.

The E-shape and A-shape grips are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play dominant eleventh chords on other roots.

Inversions of Eb11

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.

Where Eb11 fits

Eb11 is V11 in Ab major. The eleventh, Ab, is the same note as the fourth of a sus chord and wants to fall to the third G; that is why the third is usually left out, and why Eb11 works as a softer V that delays the pull home. It often moves to Eb7 before the tonic.
