Issue:

Double-click the block attribute will open Enhanced Attribute Editor where you can edit the values for the block attribute. But how can we edit the block attribute definition?

Solution:

  1. Similar to a block reference, the block attribute is edited through Block Editor (command: BEDIT) or Edit Block In-place (command: REFEDIT).
  2. Select the attribute block, then right-click to select either Block Editor or Edit Block In-place to edit the block attribute definition.
