9+ Obsidian Dataview: Hide Empty Query Results

Conditional show of dynamic content material inside notes, generated from the be aware’s metadata and content material utilizing a question language, might be achieved by way of intelligent use of inline JavaScript inside Dataview queries. This permits the question outcomes to be evaluated, and if no outcomes match the offered standards, the whole output, together with any surrounding markup, might be suppressed. As an example, a DataviewJS question can examine for the presence of particular key phrases or tags inside a be aware, and render content material solely when these circumstances are met. A sensible instance entails displaying a selected part of a challenge overview be aware provided that the challenge is marked as “energetic.”

This dynamic management over content material visibility affords vital benefits for be aware group and information administration. It permits for the creation of versatile and adaptable templates that alter their output primarily based on the information inside every be aware. This minimizes muddle and presents solely probably the most related data, streamlining workflows and enhancing the usability of interconnected notes. Traditionally, attaining such dynamic habits required extra advanced workarounds or third-party plugins, however with the combination of JavaScript into Dataview, this performance turns into extra readily accessible.
