Implementation: Building the Dropdown

Step 2: Create a Dropdown Component with Styled Components

In your src folder, create a new file named Dropdown.js. This file will contain all the markup and styling for your dropdown component.

Dropdown.js

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

// Styled Components for Dropdown
const DropdownContainer = styled.div`
  position: relative;
  display: inline-block;
`;

const DropdownButton = styled.button`
  background-color: #007bff;
  min-width: 300px;
  color: white;
  padding: 10px 20px;
  font-size: 16px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
  transition: background-color 0.3s ease;

  &:hover {
    background-color: #0056b3;
  }
`;

const DropdownContent = styled.div`
  display: ${(props) => (props.isOpen ? "block" : "none")};
  position: absolute;
  background-color: #f9f9f9;
  box-shadow: 0px 8px 16px rgba(0, 0, 0, 0.2);
  border-radius: 5px;
  min-width: 300px;
  z-index: 1;
  transition: opacity 0.3s ease;
  overflow: hidden;

  & a {
    color: black;
    padding: 12px 16px;
    text-decoration: none;
    display: block;

    &:hover {
      background-color: #f1f1f1;
    }
  }
`;

// Dropdown Component
const Dropdown = () => {
  const [isOpen, setIsOpen] = useState(false);

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

  return (
    <DropdownContainer>
      <p style={{ textTransform: "uppercase", fontWeight: "bold" }}>
        simple dropdown
      </p>
      <DropdownButton onClick={toggleDropdown}>Select an Option</DropdownButton>
      <DropdownContent isOpen={isOpen}>
        <a href="#option1">Option 1</a>
        <a href="#option2">Option 2</a>
        <a href="#option3">Option 3</a>
      </DropdownContent>
    </DropdownContainer>
  );
};

export default Dropdown;

Step 3: Add and Test the Dropdown Component

To see your dropdown in action, add it to your main App.js file.

App.js

import React from "react";
import "./styles.css";
import Dropdown from "./Dropdown";
import DropdownTwo from "./DropDownTwo";
import ArrowDropdown from "./ArrowDropdown";
import DropdownWithSubitems from "./DropdownWithSubitems";

export default function App() {
  return (
    <div
      style={{
        display: "flex",
        flexDirection: "column",
        gap: "30px",
        justifyContent: "center",
        alignItems: "center",
        marginTop: "50px",
      }}
    >
      <Dropdown />
    </div>
  );
}
