Repeat endings are placed above the staff at the same positions as other system-attached items, and their hooks align with barlines. They are commonly positioned outside of other notations, but some long items, such as gradual tempo changes, can be placed above repeat endings.
You can move repeat endings to different rhythmic positions in Write mode.
You can move each repeat ending segment graphically in Engrave mode and independently of other segments in the repeat ending; however, this does not change the rhythmic positions to which they are attached.
In Engrave mode, each repeat ending segment has two square handles, one at the start and one at the end.
If repeat ending segments cross system and frame breaks, you can move the segments on each side of the break independently.
In Dorico Elements, repeat endings are categorized as system-attached items. Therefore, repeat endings follow your per-layout settings for the visibility and positioning of system-attached items.
