How to build Responsive Power Apps | Responsive Layouts, Tabs, Galleries & Forms
Reza Dorrani
Overview
This video demonstrates how to build fully responsive Power Apps using container controls, enabling dynamic adjustments to screen size and orientation. It covers creating responsive headers, tabs, galleries, and forms, showcasing a service desk application as a practical example. The tutorial details how to leverage the screen size property and container settings to hide or reorder elements, change layouts, and ensure a seamless user experience across devices like tablets and mobiles. Key techniques include using the `Scale to Fit` setting, flexible width/height properties, and conditional visibility based on screen size breakpoints. The video also explains how to dynamically load tabs based on user roles and implement responsive filtering and forms.

- •Controlling element positioning (horizontal/vertical alignment, justification).
- •Utilizing flexible width for elements to share available space.
- •Hiding elements based on screen size using the `Visible` property and `Screen.Size`.
- •Using a horizontal container for tabs.
- •Implementing tabs using a gallery control.
- •Loading tab data dynamically into a collection using `ClearCollect` in `App.OnStart`.
- •Configuring gallery template items (labels, icons, selection indicators).
- •Making tab selection dynamic using variables and conditional visibility.
- •Adding vertical galleries within the main section container.
- •Using `Stretch` alignment for galleries to fill available space.
- •Adjusting gallery `WrapCount` based on `Screen.Size` for responsiveness.
- •Filtering gallery items dynamically based on selected tab and user input.
- •Creating card-like layouts for gallery items.
- •Using nested containers to group filter controls.
- •Applying `Wrap` property to containers to allow controls to reflow.
- •Dynamically adjusting container heights based on `Screen.Size`.
- •Filtering gallery data using `Filter` function based on dropdown and text input values.
- •Making filter sections visible only for specific tabs.
- •Using the Edit Form control.
- •Connecting the form to the data source.
- •Enabling `WidthFit` on data cards for automatic resizing.
- •Setting the form's `ColumnCount` property.
- •Navigating to the form screen and displaying selected item details.
- •Loading tabs dynamically into a collection based on user roles or conditions.
- •Checking user permissions (e.g., group membership) to determine tab visibility.
- •Example: Hiding the 'Assigned to Me' tab if the user has no assigned tasks.
Key Takeaways
- 1Responsive design in Power Apps is achieved using container controls and understanding screen size breakpoints.
- 2The `Screen.Size` property is crucial for conditionally showing/hiding elements and adjusting layouts.
- 3Flexible width and height properties within containers allow elements to adapt to available space.
- 4Galleries can be made responsive by adjusting `WrapCount` based on `Screen.Size` and using formulas for element positioning.
- 5Nested containers and the `Wrap` property are effective for creating responsive filter sections.
- 6Forms can be made responsive by enabling `WidthFit` on data cards and adjusting `ColumnCount`.
- 7Dynamic tab loading based on user roles or data conditions enhances personalization and app efficiency.
- 8Disabling 'Scale to Fit' in app settings is a prerequisite for effective responsive container usage.
