How is a filter pane created in a Qlik Sense app?

A filter pane in a Qlik Sense app is created by adding a filter pane visualization and choosing a specific dimension that you want to filter by. This process involves selecting a dimension from the data model to allow users to filter their data dynamically based on that dimension. The filter pane provides an interactive way for users to explore the data by selecting or deselecting values within that dimension, which then affects the data displayed across other visualizations in the app.

The other methods mentioned do not specifically create a filter pane. Importing external data pertains to data loading and preparation, which is a different aspect of data management rather than visualization. Selecting any sheet from the main dashboard simply navigates through the app without creating any new visualizations. Applying sorting options affects the arrangement of data within existing visualizations but does not create a filter pane. Therefore, the correct approach for creating a filter pane involves directly adding it as a visualization and associating it with a chosen dimension.
