Filter

The primary purpose of filters is to improve the user experience by helping users quickly find the information they are looking for without having to search through irrelevant content.
Filters are typically used for the following cases:

• Refining search results: Filters allow users to narrow down search results by applying various criteria, such as price range, color, size, brand, or any other relevant attributes like crops or active ingredients. This helps users quickly find the products or information they are interested in without having to browse through a large number of irrelevant results.

• Exploring and navigating content: Filters can be used to navigate and explore large data sets or collections of content. For example, on a news website, filters can be used to sort articles by category, date, author, or popularity, making it easier for users to find the content that interests them.
  

Filters can be implemented in various forms, such as dropdown menus, checkboxes, sliders, text inputs, or any other suitable user interface controls. 

The design and implementation of filters should follow best practices to ensure a seamless and intuitive user experience, such as providing clear labels, logical grouping, and real-time feedback on the number of results or items matching the applied filters.
