Create A Vue Popover Under Search Bar: A Complete Guide

Table of Contents :

Creating a popover under a search bar in a Vue.js application can greatly enhance the user experience by providing contextual help or suggestions. This guide will walk you through the process step by step, from setting up your Vue project to implementing the popover functionality. Let’s dive in! 🎉

What is a Popover? 🤔

A popover is a small overlay that displays additional information when a user interacts with an element, such as a search bar. It can contain text, links, buttons, and other interactive elements, making it a versatile tool for user engagement.

Prerequisites 📋

Before we get started, ensure you have the following:

  • Basic understanding of Vue.js
  • A working environment with Node.js and Vue CLI installed
  • Familiarity with HTML and CSS

Setting Up Your Vue Project 🛠️

  1. Create a New Vue Project:

    Open your terminal and create a new Vue project using Vue CLI:

    vue create vue-popover-example

    Change into your project directory:

    cd vue-popover-example

  2. Install Dependencies:

    You might want to use a UI framework like BootstrapVue or Vuetify to help style your popover. For this guide, we’ll use BootstrapVue:

    npm install bootstrap-vue

  3. Configure BootstrapVue:

    Open src/main.js and include BootstrapVue:

    import Vue from 'vue'
import App from './App.vue'
import { BootstrapVue, IconsPlugin } from 'bootstrap-vue'
import 'bootstrap/dist/css/bootstrap.css'
import 'bootstrap-vue/dist/bootstrap-vue.css'

Vue.use(BootstrapVue)
Vue.use(IconsPlugin)

new Vue({
  render: h => h(App),
}).$mount('#app')

Building the Search Bar and Popover 🔍

Now, let's create a search bar that triggers a popover.

  1. Create a New Component:

    Create a new Vue component named SearchBar.vue in the src/components directory.

  2. Adding the Component to Your App:

    Now that we have our SearchBar component, let's use it in our main App.vue:

Explanation of the Code 📖

  • Search Input: The <b-form-input> component is used to create a search input box. The v-model directive binds the input value to searchQuery.
  • Popover Component: The <b-popover> component from BootstrapVue is used to create the popover. We use the v-if directive to conditionally render the popover when showPopover is true.
  • Suggestions: The filteredSuggestions computed property filters the suggestions based on the current input in the search box.
  • Popover Visibility: The popover is shown on focus of the input and hides on blur. A timeout is added to allow for interaction with the popover itself.

Styling the Popover 🎨

You may want to customize the appearance of the popover. You can do this by adding your styles to the <style> section of SearchBar.vue. Here’s an example:

.popover {
  background-color: #f9f9f9;
  border: 1px solid #ddd;
  border-radius: 4px;
}

.popover ul {
  list-style: none;
  padding: 0;
}

.popover li {
  padding: 5px 10px;
}

.popover li:hover {
  background-color: #e9ecef;
  cursor: pointer;
}

Testing Your Component 🧪

After completing your implementation, run your Vue application:

npm run serve

Open your browser and navigate to http://localhost:8080. You should see your search bar, and when you click on it or focus on it, the popover should appear below the search bar with filtered suggestions based on your input. 🎉

Conclusion 🏁

In this guide, we covered how to create a popover under a search bar using Vue.js and BootstrapVue. By following the steps outlined above, you can enhance your application with a feature that helps users find what they need more effectively.

Key Takeaways:

  • A popover is a great way to offer context-specific information or suggestions to users.
  • Vue.js makes it easy to create interactive components with computed properties and directives.
  • BootstrapVue provides components like popovers and form inputs that enhance the look and feel of your application.

We hope this guide has been helpful in understanding how to implement a popover in your Vue applications. Happy coding! 🚀
