How can I hide a block of questions based on a URL parameter from the table of contents

helllo,

I'm distributing a survey with unique URLs for each respondent. The URLs include parameters like `r1=1`, `r4=1`, etc., where each `r` represents a specific information requirement. These requirements may include multiple questions grouped within a block.

• My goal: I want to hide the block of questions corresponding to a specific requirement if the corresponding parameter is present in the URL (e.g., hide the block for `r1` if `r1=1` is present).

• My question: How can I achieve this? Is there a way to use JavaScript or other methods within Qualtrics to dynamically hide blocks based on URL parameters.

I would appreciate any guidance or suggestions from the community on how to achieve this.

Thank you!
