Data bindings
Manage a selected layer's data links under Properties → Data Bindings. Binding indicators are not drawn over the canvas artwork. + Add Binding creates a new data field for the next unbound property and binds it immediately, even when the project has no fields yet. The new field starts with that property's current value, so adding the binding does not change the graphic. Choose a different existing field in the binding's Field menu if you want to reuse one, or open Data to rename and edit the new field.
Bound controls remain editable in Properties. Designer edits update the bound field's default without removing its data link; a mapped control updates the active option's mapping instead. Double-click text on the canvas to edit it directly, including nested and mapped bindings. These edits are saved and undoable. An edited test-data leaf returns to its authored default while unrelated preview values remain available. Playout can still override the values at runtime.
Editable in playout
To let playout change a text or image layer, turn on Properties → Editable in playout. Studio creates a data field named after the layer, starting with its current text or image, and binds it, so the graphic doesn't change until playout sends a value. Turning it off removes the binding and the field, unless another layer or rule still uses it.
