User Interface Elements Every Designer Should Know

BlogHeader UIElements 1200x600

UI elements or user interface elements are the most integral part of product design, regardless of whether it’s a web design or mobile, desktop, or Augmented Reality or Virtual Reality app. UI elements are the core building blocks for all products.

As a UI designer or web developer, it’s crucial to have a deep understanding of UI elements and how users interact with them. It will help you create a better application/website structure.

Designers don’t usually draw UI elements anew when they’re building web pages or mobile apps. They usually start with a ready repository of UI elements, and if they’re backed with code, interactive UI components.

UXPin Merge allows you to bring those components to UXPin’s design editor and build fully functional UIs in minutes instead of hours, thus optimizing the workflow of the whole product team. Learn more about UXPin Merge.

What are UI Elements?

To put it simply, user interface elements are the building blocks of apps and web sites. They are what users interact with when they are using the product. They click on a button to sign up, they use navigational components to switch between pages, etc.

UI elements are what allows for good user experience and well-designed functionalities.

UX design rests on design patterns that your users are familiar with. If you break a design pattern, users may get lost or confused at least. Designers use well-known UI elements to prevent that.

Learning what are UI elements is not enough. You also need to know the context of use.

3 Types of UI Elements

Ideally, we can group UI elements into 3 major categories. 

  1. Input elements – users interact with them to put in their information or move to the next step.
  2. Output elements – those elements show the result of a previous user action.
  3. Helper elements – further divided into navigational, informational, and containers, they help to move through the digital product, get information, and point user’s attention to some element.

Input elements

Input elements are responsible for handling different user inputs. Sometimes they’re also part of the input validation process. Some of the most used input elements include:

  • Dropdowns
  • Combo boxes
  • Buttons
  • Toggles
  • Text/password fields
  • Date pickers
  • Checkboxes
  • Radio buttons
  • Confirmation dialogues

Output elements

Output elements are responsible for showing results against various user inputs. They also show alerts, warnings, success, and error messages to the users. Output elements aren’t neutral by nature. They rely on inputs and various operations.

Helper elements

All other elements fall into this category. The most widely-used helper elements include:

  • Notifications
  • Breadcrumbs
  • Icons
  • Sliders
  • Notifications
  • Progress bars
  • Tooltips

We can also group helper elements into 3 categories.

Navigational UI elements

Navigational components simplify moving through the site, desktop or mobile app or any other digital product. Navigational helper UI elements include things like navigation menus, list of links, breadcrumbs, to name but a few.

Informational UI elements

Responsible for representing information. These include, for example, tooltips, icons, and progress bars.

Groups or containers UI elements

Responsible for holding various components together. Widgets, containers, and sidebars for part of this category. The Newsletter subscription widget of UXPin blog is also a good example of a container.

9 Common Input UI Elements

Here are nine of the most common input elements that every designer should know about. This list includes buttons, checkboxes, text fields, and you’re certain to find them in the most popular design systems, listed under UI components.


Checkboxes allow the user to select one or more options from an option set. It is best practice to display checkboxes vertically. Multi-columns are also acceptable considering the available space and other factors.

Checkboxes are UI elements that many websites and apps use


Dropdowns allow users to select one item at a time from a long list of options. They are more compact than radio buttons. They also allow you to save space. For better UX, it’s necessary to add a label and a helper text as a placeholder. I.e. “Select One, Choose, etc.”

Combo boxes

Combo boxes allow users to either type a custom value directly or select a value from the list. It is a combination of a drop-down list or list box and a single-line input field.

Buttons allow the users to perform an action with touch or click. It is typically labelled with text, icon, or both. Buttons are one of the most important parts of a UI. So it’s important to design a button that the user will actually click.

Toggles allow the user to change a view/value/setting between two states. They are useful for toggle between on and off state or switching between list view and grid view.

Text and password fields

Text fields and password fields allow users to enter text and password respectively. Text fields allow both single-line and multi-line inputs. Multi-line input fields are also known as “textarea”. Password fields generally allow single lines for a password.

Forms are awesome examples of UI elements

Date pickers

A date picker allows users to pick a date and/or time. By using a native date picker from the platform, a consistent date value is submitted to the system.

Radio buttons

Radio buttons allow users to select only one of a predefined set of mutually exclusive options. A general use case of radio buttons is selecting the gender option in sign-up forms.

4 Common output elements

Alert UI Element

Toast UI element

This refers to a UI feature where an event (user input, server response, calculation etc.) triggers a small text box to appear on the screen. Ideally, it appears at the bottom on mobile and bottom left or right side on the desktop.

The difference between “Alert” & “Toast” is that the former doesn’t dismiss itself and the latter does after a certain time.

This feature generates a small badge to the top-right of its child(ren). In general, it represents a small counter or indicator. This can be something like the number of items over the cart icon or online indicator over a  user avatar.

Charts are a common way of expressing complex data sets because they depict different data varieties & data comparisons.

The type of chart used in UI depends primarily on two things: the data we want to communicate, and what we want to convey about that data

List of links are other UI elements


Breadcrumbs allow users to see their current location within the system. It provides a clickable trail of proceeding pages to navigate with.

This UI element is a breadcrumb.

Search fields

A search bar is usually made up of two UI elements: an input field and a button. It allows users to enter a keyword and submit it to the system expecting the most relevant results.

How would you separate certain elements from the rest? That is what groups and containers are for.


It’s an element of interaction, like a chat window, components of a dashboard, or embeds of other services.

UI Containers

Containers hold different components together. This includes text, images, rich media etc. Cards in modern UI design are one of the best examples of containers. 

UI containers are common UI elements. This one comes from material design


Sidebars also contain other groups of elements and components. But that can be switched between collapse and visible state.
