Creating Reusable Page Templates in OutSystems with a Shared Header and Footer

OutSystems allows developers to create responsive applications with reusable components efficiently. This comprehensive guide will walk you through creating reusable page templates in OutSystems, featuring a shared header and footer. This ensures consistency across your web application, making maintenance and updates a lot easier.

Prerequisites

• An active OutSystems account with access to a development environment.
• Basic knowledge of the OutSystems Service Studio interface and terminology, including modules, themes, and widgets.
• A project where you want to implement reusable page templates.

Understanding Page Templates in OutSystems

• Page templates in OutSystems are reusable components designed to maintain consistent layout and design across multiple pages.
• These templates should include elements that appear consistently across pages, such as headers and footers.

Creating a New Theme for Your Template

• Open OutSystems Service Studio and navigate to the Interface tab.
• Click on "UI Flows" and select "Theme".
• Create a new theme by duplicating an existing one or starting from scratch.
• Name your theme for easy identification (e.g., "SharedLayoutTheme").
• Customize the theme to set default styles for your pages, such as fonts, colors, and margins.

Designing the Header and Footer

• Navigate to the Interface tab and select "Web Blocks".
• Create a new Web Block for the header. Name it (e.g., "SharedHeader").
• Inside the "SharedHeader" Web Block, design the header with elements like logos, navigation menus, and any other components required across pages.
• Repeat the process for the footer by creating another Web Block, naming it "SharedFooter".
• Design the footer with necessary links, branding elements, or copyright notices.

Creating the Page Template

• In the Interface tab, navigate to "Web Flows" and select the desired web flow to add the template.
• Create a new Web Screen and name it (e.g., "BaseTemplate"). This will serve as your reusable page template.
• Drag and drop your "SharedHeader" and "SharedFooter" Web Blocks onto this screen to ensure consistency.
• Designate a content placeholder between the header and footer where individual page content will appear.

Using the Page Template for New Pages

• When creating a new page, duplicate the "BaseTemplate" Web Screen or designate it as a master for other screens.
• Insert specific content into the designated content placeholder between the header and footer Web Blocks on individual pages.
• This ensures each page maintains a consistent header and footer while having unique content.

Testing and Publishing the Template

• Preview the pages using the template to ensure that headers and footers display consistently across pages.
• Make adjustments to the header, footer, or design elements within the template as required.
• Publish the application and verify that shared components maintain their consistent appearance and functionality.

Maintaining and Updating the Template

• Regularly review your header and footer for updates such as new links or branding changes.
• Update the "SharedHeader" and "SharedFooter" Web Blocks as necessary. These changes will automatically propagate across all pages using the template, reducing duplicated effort.
• Ensure that CSS styles and scripts in your theme remain relevant and well-organized.

By following these steps, you can create a cohesive application layout in OutSystems with reusable page templates that incorporate a shared header and footer. This practice not only aligns with best design principles but also reduces development time and maintenance effort by ensuring consistent page structures across your application.
