Working with Layers
Last updated on 2026-05-11
Overview
In XBRL Tagger, layers allow you to apply different tags to the same text block more than once. Because tags within one layer must not overlap, you can add another layer for overlapping tagging ranges. This is useful when, for example, a paragraph has to be tagged with two different taxonomy elements.
Each document in XBRL Tagger has two predefined layers by default: a default layer for text and a default layer for tables.
In the editor, only the tags of the active layer are displayed. You can create and manage additional layers in the Layer Manager.
This article contains the following sections:
Default Layers in XBRL Tagger
In the XBRL Document workspace, two tabs at the top of the document area allow you switch between layers for text tagging and table tagging:
- Text tagging: Activates the layer for text tagging. Table tags are hidden and only text tags are displayed.
- Table tagging: Activates the layer for table tagging. Text tags are hidden and only table tags are displayed.

In the Layers drop-down list, you can add, edit, or delete layers. To add a layer:
Open the drop-down list Layers and click Add new text layer.
Enter a name for the new layer, then click Save layer.

To switch to a different level, follow these steps:
Open the Layers drop-down list.
