What do you need to append to the URL of a Power BI Dashboard to collapse the navigation pane by default?

To collapse the navigation pane by default in a Power BI Dashboard, adding ?collapseNavigation=true to the URL is the correct approach. This parameter specifically instructs Power BI to render the dashboard with the navigation pane minimized when the page loads.

The functionality provided by this parameter is particularly useful when sharing dashboards in presentations or when it's important to focus the user's attention on visualizations without the distraction of the navigation pane. By using true as the value, you ensure that the navigation pane does not appear at the start, enhancing the visual experience.

The other options do not have the correct syntax or keyword to produce the desired effect. Understanding the precise URL parameters and their effects is crucial for effectively customizing the user interface in Power BI. The use of true/false syntax allows for straightforward control over the display elements of the dashboard, making it an essential skill for anyone looking to optimize their Power BI presentations or shared dashboards.
