# Conditional Visibility Allow data-binding in a conditional visibility sense, where any element can be hidden or shown based on a truthy value. ## Use Cases Display a thank you section only if the querystring has the `#subscribed` hash. Optionally, auto-scroll to it. e.g. the SA5 newsletter sign-up Show a section only if a referral code is detected ( webStorage, cookie, etc. ) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://attr.sygnal.com/sa5-data/binding-data/conditional-visibility.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
