What is a Filter?
A Filter is a user interface element that allows users to refine or narrow down a large set of data or options based on specific criteria. Filters are commonly used in e-commerce sites, search engines, and data dashboards to help users find relevant information quickly.
Effective filter design is essential for enhancing user experience, especially when dealing with complex data sets. Filters should be intuitive, easy to use, and provide clear feedback to users on how their selections are affecting the results. Common types of filters include checkboxes, dropdowns, sliders, and search fields.
