Stylish JavaScript Dropdowns With Styled Components

Table of Contents :

Creating stylish JavaScript dropdowns can enhance the user experience and give your web application a modern look. Leveraging Styled Components is an effective way to achieve this while maintaining a clean codebase. In this article, we will walk through how to implement stylish dropdowns using Styled Components in React.

Understanding Dropdowns in JavaScript

What is a Dropdown?

A dropdown is a graphical control element that allows the user to choose one value from a list. Users click on a button to see a list of options, and they can select an item from this list. Dropdowns are widely used in forms and navigation menus.

Importance of Stylish Dropdowns

Stylish dropdowns do not only improve aesthetics but also significantly enhance usability. A well-designed dropdown is easy to interact with and can convey the functionality of your application better than plain dropdowns.

Getting Started with Styled Components

What are Styled Components?

Styled Components is a library for React and React Native that allows you to use component-level styles in your application. It utilizes tagged template literals to style your components. This means you can write plain CSS in your JavaScript code.

Setting Up Your Project

To get started, you need to have Node.js and npm installed on your machine. Here’s how to set up a new React project with Styled Components:

  1. Create a new React application:

    npx create-react-app stylish-dropdowns
cd stylish-dropdowns

  2. Install Styled Components:

    npm install styled-components

Creating the Dropdown Component

Now that we have our project set up, let’s create a dropdown component.

  1. Create a new file named Dropdown.js in the src folder.

  2. Implement the Dropdown Component:

import React, { useState } from 'react';
import styled from 'styled-components';

const DropdownContainer = styled.div`
  position: relative;
  display: inline-block;
`;

const DropdownButton = styled.button`
  background-color: #6200ee;
  color: white;
  padding: 10px 15px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
  font-size: 16px;
  
  &:hover {
    background-color: #3700b3;
  }
`;

const DropdownList = styled.ul`
  position: absolute;
  top: 100%;
  left: 0;
  background-color: white;
  border: 1px solid #ccc;
  border-radius: 5px;
  margin: 5px 0 0;
  padding: 0;
  list-style: none;
  z-index: 1;
`;

const DropdownItem = styled.li`
  padding: 10px 15px;
  cursor: pointer;

  &:hover {
    background-color: #e0e0e0;
  }
`;

const Dropdown = () => {
  const [isOpen, setIsOpen] = useState(false);
  const options = ["Option 1", "Option 2", "Option 3"];

  const toggleDropdown = () => {
    setIsOpen(!isOpen);
  };

  return (
    
      
        Select an option
      
      {isOpen && (
        
          {options.map((option, index) => (
            
              {option}
            
          ))}
        
      )}
    
  );
};

export default Dropdown;

Explanation of the Code

  • Styled Components: We created several styled components (DropdownContainer, DropdownButton, DropdownList, and DropdownItem) to define the structure and style of our dropdown.
  • State Management: We used the useState hook to manage whether the dropdown is open or closed.
  • Rendering the Dropdown: We conditionally render the dropdown list based on the state.

Integrating the Dropdown Component

To use the Dropdown component, simply import it into your main application file, usually App.js.

import React from 'react';
import Dropdown from './Dropdown';

const App = () => {
  return (

  );
};

export default App;

Enhancing the Dropdown Functionality

Handling Item Selection

To make the dropdown more interactive, we can add a function to handle item selection.

  1. Update the Dropdown component to include a handleSelect function:
const handleSelect = (option) => {
  alert(`You selected ${option}`);
  setIsOpen(false);
};
  1. Call this function when rendering the DropdownItem:
 handleSelect(option)}>
  {option}

Adding Keyboard Accessibility

Accessibility is an important aspect of web development. We can improve our dropdown by allowing users to navigate it using the keyboard.

  1. Add keydown events to the DropdownButton to toggle and navigate through items:
const handleKeyDown = (event) => {
  if (event.key === 'Enter') {
    toggleDropdown();
  }
};

return (
  
    Select an option
  
);

Final Code for the Dropdown Component

Here’s the final version of the dropdown component with all enhancements:

import React, { useState } from 'react';
import styled from 'styled-components';

const DropdownContainer = styled.div`
  position: relative;
  display: inline-block;
`;

const DropdownButton = styled.button`
  background-color: #6200ee;
  color: white;
  padding: 10px 15px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
  font-size: 16px;

  &:hover {
    background-color: #3700b3;
  }
`;

const DropdownList = styled.ul`
  position: absolute;
  top: 100%;
  left: 0;
  background-color: white;
  border: 1px solid #ccc;
  border-radius: 5px;
  margin: 5px 0 0;
  padding: 0;
  list-style: none;
  z-index: 1;
`;

const DropdownItem = styled.li`
  padding: 10px 15px;
  cursor: pointer;

  &:hover {
    background-color: #e0e0e0;
  }
`;

const Dropdown = () => {
  const [isOpen, setIsOpen] = useState(false);
  const options = ["Option 1", "Option 2", "Option 3"];

  const toggleDropdown = () => {
    setIsOpen(!isOpen);
  };

  const handleSelect = (option) => {
    alert(`You selected ${option}`);
    setIsOpen(false);
  };

  const handleKeyDown = (event) => {
    if (event.key === 'Enter') {
      toggleDropdown();
    }
  };

  return (
    
      
        Select an option
      
      {isOpen && (
        
          {options.map((option, index) => (
             handleSelect(option)}>
              {option}
            
          ))}
        
      )}
    
  );
};

export default Dropdown;

Adding Styling Variations

To make your dropdown even more stylish, you can experiment with different styles. Here are some ideas:

  • Custom Colors: Change the background color of the dropdown button and items.
  • Font Style: Use different font families and weights to give it a unique look.
  • Transitions: Add CSS transitions to smooth the dropdown opening and closing animations.

Example of Adding Transitions

You can enhance the dropdown using CSS transitions as follows:

const DropdownList = styled.ul`
  transition: all 0.3s ease-in-out;
  /* other styles */
`;
