Power Apps Dropdowns: Top Table Tips You Need Now

Key insights

• Dropdown control in Power Apps lets users select from a list of options, and its Items property must be set to a Table containing the choices. You can generate this table using functions like Table, AddColumns, Sequence, Distinct, or by connecting directly to data sources such as SharePoint.


• The video demonstrates how to use the PowerFX Table function, which creates custom lists for dropdowns, and explains how to show multiple fields with AddColumns. It also covers making dynamic items with the Sequence function.


• Collections are covered as a way to store and manage data locally within your app. These collections can feed dropdowns for faster access and offline scenarios.


• You learn how to link dropdowns directly to external Data Sources, such as SharePoint lists, which allows real-time updates and easy data management without manual entry.


• The guide offers tips on using properties like Dropdown1.Selected.Value for retrieving user selections, applying the SortByColumns function for organized displays, and adding an “All” option for broader selection capability.


• The video introduces the Choices function, which pulls options from related tables or lookup columns, making it easier to create dependent dropdowns in complex apps.

Introduction: Exploring Power Apps Dropdowns and Tables

Shane Young, a recognized Microsoft Most Valuable Professional (MVP), recently released a comprehensive YouTube video aimed at demystifying the use of dropdown controls and tables in Microsoft Power Apps. In his detailed walkthrough, he focuses on the essential Items property of the dropdown control, guiding viewers through various methods to generate the required data tables. As organizations increasingly rely on Power Apps for custom business solutions, understanding these controls is crucial for both newcomers and experienced users.

The video serves as a practical resource for anyone looking to enhance their Power Apps skills, whether they are building their first app or optimizing an existing one. By breaking down complex concepts into approachable segments, Shane ensures that viewers can apply these techniques in real-world scenarios.

Understanding the Items Property and Table Generation

A major focus of Shane’s video is the Items property of the dropdown control, which determines what appears in the dropdown list. The property requires a table of data, and Shane demonstrates several ways to construct this table using PowerFX functions. For example, he covers the use of the Table function for static data, as well as more dynamic approaches like Sequence and AddColumns for generating lists on the fly.

Moreover, Shane highlights scenarios where data comes from external sources, such as SharePoint lists or collections. He explains how to pare down large datasets to display only relevant options in the dropdown, a technique that improves both performance and user experience. These methods offer flexibility but also require careful planning to balance simplicity and scalability.

Integrating Data Sources and Leveraging PowerFX Functions

The video delves into integrating dropdowns with various data sources, including SharePoint and Dataverse. Shane explains that connecting directly to these sources can streamline app development, but it may introduce challenges related to data refresh rates and delegation limits. As a result, he suggests using collections or filtered queries to maintain responsiveness while ensuring the dropdown remains up-to-date.

Additionally, Shane explores advanced PowerFX functions such as Distinct—helpful for removing duplicate values—and Choices for working with choice fields in SharePoint or Dataverse. These functions empower developers to build dropdowns that reflect real-time business data, yet they must be used judiciously to avoid slowing down the app or overwhelming users with too many options.

Enhancing User Experience: Sorting, Selection, and Customization

A crucial aspect of Shane’s guide is improving the user experience by customizing dropdown behavior. He demonstrates how to access the selected item using Dropdown1.Selected.Value, which is essential for triggering actions based on user choices. Furthermore, he shows how to sort options alphabetically or by other criteria using SortByColumns, making it easier for users to find what they need.

Shane also offers tips for displaying multiple fields in the dropdown by using AddColumns, thus providing more context for each option. Another practical tip is adding an “All” option to the dropdown, enabling users to view or select all available records at once. These enhancements can make an app more intuitive but may require extra logic to handle complex scenarios or large datasets.

Balancing Flexibility, Performance, and Usability

Throughout the video, Shane emphasizes the tradeoffs involved in designing dropdowns and tables. While connecting directly to data sources offers real-time updates, it can impact performance and hit delegation limits—especially with large lists. Conversely, using collections or filtered tables improves speed but may require periodic refreshes to stay current.

Developers must weigh these factors carefully, striving to balance flexibility with performance and usability. Customizing dropdowns and integrating them with tables can provide a seamless experience, but only if underlying data structures and logic are optimized for the app’s specific needs.

Conclusion: Key Takeaways for Power Apps Developers

In summary, Shane Young’s YouTube video serves as a valuable resource for anyone looking to master dropdowns and tables in Power Apps. By covering everything from basic table creation to advanced data integration and user interface enhancements, he equips developers with the knowledge to build effective, efficient, and user-friendly applications.

As the Power Platform evolves, staying informed about best practices and new features remains critical. Shane’s guide reinforces the importance of understanding both technical options and practical tradeoffs, empowering Power Apps creators to deliver solutions that truly meet their organization’s needs.
