For a tag that requires two labels with conditional visibility, which parameter type should be used?

In the context of Revit, when dealing with tags that require conditional visibility based on certain parameters, the most effective choice for the parameter type is Yes/No. This type of parameter allows you to create a binary condition that can either be true or false.

For example, if you want to display one label when a condition is met (i.e., the parameter is set to Yes) and another label when it is not met (i.e., the parameter is set to No), using a Yes/No parameter provides the necessary control to implement this logic within the tagging system.

By defining the conditional visibility in the tag family using Yes/No parameters, users can ensure that only the desired labels are visible under specific circumstances, streamlining the tagging process while maintaining clarity in documentation. This functional aspect of Yes/No parameters is crucial for enhancing the interoperability and effectiveness of tags in architectural design workflows.
