In Trilium, attributes can be automatically inherited by child notes if they have the isInheritable flag set to true. This means the attribute (a key-value pair) is applied to the note and all its descendants.
The archived label can be set to be inheritable, allowing you to hide a whole subtree of notes from searches and other dialogs by applying this label at the top level.
Copying inheritance differs from standard inheritance by using a child: prefix in the attribute name. This prefix causes new child notes to automatically receive specific attributes from the parent note. These attributes are independent of the parent and will persist even if the note is moved elsewhere.
#child:attributeName#child:child:attributeName, where each child down the hierarchy receives the appropriate attribute.If a parent note has the label #child:exampleAttribute, all newly created child notes will inherit the #exampleAttribute label. This can be useful for setting default properties for notes in a specific section.
Attributes can also be inherited from templates. When a new note is created using a template, it inherits the attributes defined in that template. This is particularly useful for maintaining consistency across notes that follow a similar structure or function.
