    How to use the Align Center UI Pattern

    This example shows you how to center align a user's name and initials.

    1. In Service Studio, in the Toolbox, search for Align Center.

      The Align Center 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 Align Center widget into the Main Content area of your application's screen.

      By default, the Align Center widget contains a Content placeholder.

    3. From the Toolbox, drag the User Avatar pattern into Content placeholder.

    4. On the Properties tab, in the Name property, enter a name. In this example, we enter Scott Richie.

    5. Add any other relevant content to the Content placeholder. In this example we add some text (Scott Richie) and an image.

    6. On the Align Center Properties tab, you can set the content's orientation (either vertical or horizontal).

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