Selecting tags

Collections, rules, dashboards, and derived tags all pick their tags by path, so where a component sits in the tag tree decides how its tags are selected. The Tag tree path setting places a component in the tree, and tag expressions such as tag.MatchesPath("Vehicles/Car1") select tags by that path, value, or quality.

• Tag tree paths and dashboard binds: how nesting a component in a folder of the tag tree affects scopes and dashboard binds.
• Nest a component in the tag tree: set the Tag tree path of a component, and change it safely on a deployed component.
• Tag expressions: look up the expression language shared by collections, rules, and derived tags.
• Build an expression with the guided builder: assemble a tag expression from a form in the collections and rules editors.

To put a selection to use, refer to Collections and Tag rules.
