Menu Filtering

CommCare allows you to intelligently filter menus in your application based on standard XPath Expressions. This article walks through filtering menus, but filters can also be used on individual questions.

Enabling Menu Filtering

To enable menu filtering, you first need to enable the Display Conditions Add-Ons. Select the gear icon next to the application name in the upper left hand corner. Then select the tab.

Open

Select the three lines on the right hand side and select the 'Calculations' option if it is not already displayed.

Open

Note that you must change your CommCare version to 2.20 or later in the Application Settings AND you must be using CommCare mobile 2.20 or later in order to use a Menu Filter.

Another example is when you want to use your app in several countries and only show specific content to users from each country. For example when deploying an app to India, Senegal, and Zamba, the user property country would be set to either India, Senegal, or Zambia for each user. If I want to show the module to users from only Senegal and Zambia I would create the following XPath expression:
