Filters
Overview
Description
Filters are a UI element that helps users narrow down large datasets to find specific information quickly, improving usability and efficiency.
Key components
Key components of filters include controls like dropdowns, checkboxes, and sliders, as well as design best practices such as clear labeling, visible status indicators, displaying result counts, and offering a “Clear all” option. Common filter layouts include sidebar filters, top filter bars, and inline “chips” or tags.
Uses
- Information refinement: filters help users narrow down large lists or datasets, such as product catalogs, search results, or reports, by specifying criteria like size, price, color, or status.
- Reduced cognitive load: by removing irrelevant information, filters make it easier for users to focus on the data that matches their needs, creating a more manageable and less overwhelming experience.
- Faster decision-making: in applications where users need to make quick, data-driven decisions, filters save time by quickly surfacing relevant information, eliminating the need to manually sift through irrelevant result
Value to user
- Enhance usability: filters simplify complex data by allowing users to define criteria and extract only relevant information, avoiding information overload.
- Increase efficiency: users can quickly find what they need without manually scrolling through extensive lists, saving time and effort.
- Improve navigation: filters provide structured pathways for users to explore and refine large content sets, such as in e-commerce, booking systems, and dashboards.
Best practices
- Visibility and placement: place filters in a logical and visible location, such as a sidebar or filter bar, to ensure they are easily accessible.
- Clear status indicators: visually show users which filters are active to provide instant feedback and clarity.
- Result counts: display the number of items available for each filter option and the total number of results after applying a filter to help users anticipate outcomes.
- “Clear all” option: provide a straightforward way for users to remove all active filters at once, allowing for easy exploration and reset.
- Logical organization: group and sort filter options in an intuitive way, perhaps by popularity or importance, to align with user expectations.
- Loading indicators: show a loading animation when filters are applied, keeping users informed that the system is working on their request.
- Filter chips/tags: use horizontal “chips” or tags to display currently selected filters, making them easy to see and deselect.
Accessibility notes
- Use proper form controls with labels.
- Provide keyboard navigation support
