What is UI Filter in UX Design?
A UI filter is a design element that allows users to narrow down a data set or options based on specific criteria. For example, we use filters for eCommerce stores to find products by size, color, price, etc. A filter UI lets users find what they want quickly, saving time and reducing frustration.
Designers design filters based on user needs to help them navigate content or offerings efficiently. When implemented correctly, filters streamline navigation, making interfaces user-friendly and intuitive.
How Do Filters Affect User Experience?
Filters empower users by controlling how they find and experience content, speeding up tasks, and enhancing engagement with digital products.
Here’s how filters enhance the user experience:
- Navigation efficiency: Users don’t waste time scrolling through irrelevant data. For example, instead of browsing through hundreds of shoes on an eCommerce site, users can filter for their size, preferred color, or brand to find the most relevant results.
- Personalized content delivery: Filters cater to individual preferences. Consider a news app; by selecting specific categories like ‘Technology’ or ‘Health,’ users receive news tailored to their interests.
- Decision-making support: Overwhelming users with options can paralyze decision-making. Filters limit choices, making it easier for users to decide. In a streaming app, rather than sifting through thousands of movies, filters can display only “Top-rated” or “New releases.”
- Reduction in cognitive load: Users don’t need to process excessive information. Filters help display only what’s necessary, ensuring users aren’t overwhelmed or fatigued.
- Improved Satisfaction and Retention: When users find what they’re looking for quickly and efficiently, they’re more likely to be satisfied and continue using the platform.
What are the Principles of User-Friendly Filter Design?
Simplicity and clarity
The filter interface should be straightforward to understand. Avoid overwhelming users with too many options or using ambiguous names. For example, an online clothing store should have clear categories like size, color, fit, brand, price, etc., rather than intricate sub-filters that confuse shoppers.
Responsiveness and feedback
Filters should apply changes quickly and give users feedback about their actions. For example, displaying a result count of the applied filters tells users how many options they must scroll through, setting expectations and preventing frustration.
Prioritization of filters
Not all filters hold the same importance. By understanding user needs, prioritize the most commonly used filters and hide the rest. For example, an accommodation filter might display the dates, guests, and location in the primary UI with a “View all filters” button or icon to access the rest.
Flexibility and control
Users should feel in command. If they make a mistake, it should be easy to rectify. For example, a “reset filters” button lets users revert to default quickly.
Visibility and accessibility
Filters must be conveniently located and accessed on a page. For example, users are used to seeing filters above results near the search field.
Designing filter user interfaces for cross-platform applications
Building filters for cross-platform applications demands awareness of varying platform-specific UI patterns and best practices. Ensuring consistent user experience across different operating systems while adhering to platform-specific guidelines is vital.
Here are some design decisions to consider when designing cross-platform filter patterns:
- iOS Platform-Specific Patterns: iOS design often uses segmented controls for filters. For instance, in a shopping app, ‘Men,’ ‘Women,’ and ‘Kids’ might be segmented controls at the top of the browsing screen.
- Android Platform-Specific Patterns: Android UIs frequently employ tabs for primary filtering options. Dropdowns are also standard for secondary filtering or sorting options.
- Consistency Across Platforms: While it’s essential to respect platform-specific patterns to maintain a native experience, ensure that the core functionality remains consistent across all platforms and mobile apps. If a filter option exists on iOS, the same should be accessible on Android, even if represented differently.
- Adaptive UI Components: Utilize components that adapt to the user’s device and operating system, providing a seamless experience regardless of device.
How to Design Effective UI Filters
Use natural language for filter options
Use words and phrases users naturally use or expect to ensure users understand filter options without ambiguity.
For example, instead of using “Canine” and “Feline” as filter options on a pet eCommerce store, use “Dogs” and “Cats”. The latter terms align more with common user language.
Provide search within filters for extensive lists
When dealing with long lists of filter options, a search function aids users in finding their choice without scrolling endlessly.
For example, an online bookstore with multiple genres provides a search bar within the filter instead of listing every genre. Users can type “thriller” and directly access that genre without navigating a lengthy list.
Utilize progressive disclosure
First, display the most commonly used filters and provide an option to see more if users need further granularity.
For example, a real estate site might show Price, City, and Price Range filters upfront with a “Show More” filtering option for users who want specifics like Bedrooms, Suburbs, and other property features.
Employ visual cues
Visual elements, like colors, icons, and typography, effectively guide users, clarify options, and enhance filter understanding.
For example, color swatches beside filter options give users a visual cue to scan results faster.
Design filters for accessibility
Filters should be usable by everyone, including those with disabilities, considering contrast, screen reader compatibility, and keyboard navigation.
For example, if your app uses color for filter categories, consider adding icons to help color-blind users navigate and scan results.
What are Some Use Cases of Good Filter UI Design?
Airbnb
Airbnb redesigned its filter UI in 2023 to be more accessible and user-friendly. Users can access the search filter overlay via a universally recognizable icon next to the search filter.
Recognizing that price is most important to users, Airbnb offers two UI design patterns for price filtering. Users can scroll to get more granular using large buttons, icons, checkboxes, sliders, and switches to apply preferences.
Booking.com
Like Airbnb, Booking.com must display millions of properties to travelers and uses filters to help narrow options. Booking.com uses a slightly different pattern with the filter icon and label to help with accessibility.
Booking.com also displays a price filter at the top and a list of popular filters below, enabling users to apply choices without too much scrolling. Beside each filter is a number displaying the amount of results per filter, providing users with helpful feedback and managing expectations.
For example, you don’t want to apply a filter and discover no properties, forcing you to return and try again–possibly several times, causing immense frustration.
Spotify
Filter doesn’t always apply to search. It can also help users decide what content they want to access. Spotify has three primary categories:
- Music
- Podcasts & Shows
- Audiobooks
The streaming service uses a button for each category on the home screen for users to filter what content they want to consume. These filters make Spotify’s home screen user-friendly and efficient because users can apply a preference in one click, eliminating the need to search or access navigation.
Amazon
Amazon’s desktop interface displays a search field at the top of the page and filters in a neatly organized left sidebar. Users can apply filters using icons, checkboxes, buttons, or form fields for custom pricing. Selecting an item automatically loads the filter results, eliminating the need for an “Apply Button,” reducing clicks and interactions.
This highly granular filtering is crucial for large databases like Amazon’s product inventory. In the example above, we apply two options in the filtering sidebar to get shoe results from over 50,000 to 202, streamlining the browsing experience to checkout faster.
Google Maps
Google Maps uses a horizontal scroll navigation pattern to display a list of common search categories. Once users apply a broad term like “Coffee,” they can use the secondary filters to apply more granularity and narrow results.
Google Maps’ filtering interface is an excellent example of how designers can help users find what they want with minimal clicks and typing, even when diverse, seemingly endless options are available.
