A label is an attribute of a note which has a name and optionally a value.

## Common use cases

- Metadata for personal use: Assign labels with optional values for categorization, such as `#year=1999`, `#genre="sci-fi"`, or `#author="Neal Stephenson"`. This can be combined with Promoted Attributes to make their display more user-friendly.
- Configuration: Labels can configure advanced features or settings (see reference below).
- Scripts and Plugins: Used to tag notes with special metadata, such as the "weight" attribute in the Weight Tracker.

## Creating a label using the visual editor

1. Go to the Owned Attributes section in the Ribbon.
2. Press the + button (Add new attribute) to the right.
3. Select Add new label for the relation.

If you prefer keyboard shortcuts, press `Alt`+`L` while focused on a note or in the Owned Attributes section to display the visual editor.

While in the visual editor:

- Set the desired name
- Optionally, set the value of the label. Labels can exist without a value.
- Check Inheritable if the label should be inherited by the child notes as well. See Attribute Inheritance for more information.

## Creating a label manually

In the Owned Attributes section in the Ribbon:

- To create a label called `myLabel` with no value, simply type `#myLabel`.
- To create a label called `myLabel` with a value `value`, simply type `#myLabel=value`.
- If the value contains spaces, then the text must be quoted: `#myLabel="Hello world"`.
- If the string contains quotes (regardless of whether it has spaces), then the text must be quoted with apostrophes instead: `#myLabel='Hello "world"'`.
- To create an inheritable label called `myLabel`, simply write `#myLabel(inheritable)` for no value or `#myLabel(inheritable)=value` if there is a value.

## Predefined labels

This is a list of labels that Trilium natively supports.

Some labels presented here end with a `*`. That means that there are multiple labels with the same prefix, consult the specific page linked in the description of that label for more information.

Label | Description
--- | ---
`disableVersioning` | Disables automatic creation of Note Revisions for a particular note. Useful for e.g. large, but unimportant notes - e.g. large JS libraries used for scripting.
`versioningLimit` | Limits the maximum number of Note Revisions for a particular note, overriding the global settings.
`calendarRoot` | Marks the note which should be used as root for Day Notes. Only one should be marked as such.
`archived` | Hides notes from default search results and dialogs. Archived notes can optionally be hidden in the Note Tree.

`run`, `runOnInstance`, `runAtHour` | See Events.
`disableInclusion` | Scripts with this label won't be included into parent script execution.
`sorted`, `sortDirection`, `sortFoldersFirst`, `sortNatural`, `sortLocale`, `top`, `bottom` | Manages automatic/permanent sorting. See Sorting Notes.
`hidePromotedAttributes` | Hide Promoted Attributes on this note. Generally useful when defining inherited attributes, but the parent note doesn't need them.

`appThemeBase` | Set to `next`, `next-light`, or `next-dark` to use the corresponding TriliumNext theme (auto, light or dark) as the base for a custom theme, instead of the legacy one. See Customize the Next theme for more information.
`cssClass` | Value of this label is then added as CSS class to the node representing given note in the Note Tree. This can be useful for advanced theming. Can be used in template notes.
`iconClass` | value of this label is added as a CSS class to the icon on the tree which can help visually distinguish the notes in the tree. Example might be bx bx-home - icons are taken from boxicons. Can be used in template notes.

`customRequestHandler` | See Custom Request Handler.
`customResourceProvider` | See Custom Resource Providers.
