Filters

The function of filters is to display the selected attributes of items that users are looking for in a specific category.

In an online clothing store, a user can quickly narrow down their selection by choosing their clothing size, preferred color, material, and price range within which they are looking for clothing.

By default, the filtering category usually includes the most common filters such as subcategories and price. All other filters largely depend on the type of items and can vary by individual categories or areas within the online store.

Recommended filtering functionalities:

Display the number of results per filter - by showing the number of filtered available items, the user can see the extent to which the results will decrease and what volume of results to expect when applying multiple filters. If there are many results, the user can further narrow down the scope by adding additional filters. If there are fewer results, the user can remove some of the less important filters.

Multi-select list - with the option to choose multiple filters in one selection, the user can select various items in one go. In the case of a wide price range between items, the user can choose multiple price ranges that are relevant to them, eliminating the need to view results only within a single price range.

Sorting filters by importance - with many filtering options, it's important to arrange them by usability, from most relevant to least relevant, to facilitate the user's selection and review of all options.

Graphic representation during selection - for some filters, you can use graphic representations of elements, which can be more understandable and clear to some users. Colors of items are more transparent when users can see the color rather than just reading its name. To do this, replace the text description with the actual color.

Limited number of choice options within a single filter - if you have a store with many options (e.g., clothing with numerous color shades), you may end up with a wide range of options within a single filter. In this case, it's best to follow a similar rule as with category selection: each selection should not contain more than eight options. For example, you can group various shades of blue, such as light blue, turquoise, navy blue, etc., under the category "blue."
