A full range of common barlines is contained in the Barlines palette.
Alternatively, you can drag a barline from the palette onto a barline in the score.
Changes are applied automatically to all barlines at the same point in the score.
Alternatively, you can hold Ctrl and drag a barline from the palette onto a barline in the score.
Only barlines in the one staff are affected.
This will add a "barline" in front of each selected note. The barline is for visual purposes and does not factor into any measure operations.
If you wish to divide a measure, inserting a real barline in the process, see Splitting a measure.
Here we are concerned with the vertical extension of barlines in order to link staves together, or their reduction to create partial barlines.
The barline snaps into place, and all other barlines in that staff follow.
Partial barlines can be easily created by adjusting "Span from" and "Span to" in the Barlines section of the Properties panel.
You can edit properties specific to barlines in the Barlines section of the Properties panel:
Style: Used to change selected barlines to one in the dropdown list.
Span to next staff: Check this to make selected barlines extend to the staff beneath.
Span from/to: used to set the vertical start and end points of one or more selected barlines.
Set as staff default: Applies the changes made in Span to next staff and Span from/to to all barlines in the staff.
Span presets: Applies the selected preset to one or more selected barlines in the score.
Selected properties for all barlines in the score can be changed in Format→Style→Barlines:
