With a module filter you can hide certain types of modules for yourself in the LMS. Suppose you are only interested in tests and test results. You can define the filter to only show these type of modules. Then in the group's results of a course for example, only the progress and scores of all tests included in the course will be visible. This makes it easier to compare these results. When you set a filter, you can indicate for each type of module if it should be shown or not. After you have set the filter, you can quickly enable or disable the filter using the filter toggle button at the top of each page. An active filter is applied to all pages in the LMS. In exported CSV files only filtered modules will be shown. The administrator may have defined a filter for you. Then you cannot change this. The administrator can also force the filter to be always active.
