  • You can use the Bottom Bar Item UI Pattern to provide access to a bottom navigation drawer and up to four actions, including the floating action button. Main pieces of core functionality are made available with one tap while allowing rapid switching between features.

    How to use the Bottom Bar Item UI Pattern

    1. In Service Studio, in the Toolbox, search for Bottom Bar Item.

      The Bottom Bar Item widget is displayed.

      If the UI widget does not display, it may be because you used a ready-made app, which deletes unused widgets from the module. To make additional widgets available in your app:

      a. Go to Module > Manage dependencies.

      b. Search for and select the relevant Producer, for example OutSystemsUI. Ensure Show All is selected.

      c. On the Public elements for the selected Producer displayed on the right, ensure Show All is selected.

      d. Search for and select the element you want to add, and click Apply.

      e. In Service Studio, in the Toolbox, search for the widget again.

    2. From the Toolbox, drag the Bottom Bar Item widget into the Bottom placeholder area of your application's screen.

      By default, the Bottom Bar Item contains Icon and Text placeholders. You can add as many Bottom Bar Items as required.

      In this example, we add another three more Bottom Bar Items.

    3. For each of the Bottom Bar Items, add the relevant content.

      In this example we add linked icons and linked text to each of placeholders.

    After following these steps and publishing the module, you can test the pattern in your app.
