Dynamic Single Chip Selections with Vue.js Drop-Down Menus : Dynamic Single Chip Selections with Vue.js Drop-Down Menus” refers to a user interface implementation that uses the Vue.js JavaScript framework to provide a dynamic and interactive drop-down menu for single chip selections. In this implementation, the drop-down menu is populated with a list of options, and the user can select only one option, which is then displayed as a chip. The dynamic aspect of this implementation is powered by Vue.js, which allows for real-time updates to the user interface based on user interactions with the drop-down menu. This design pattern offers a seamless and intuitive way for users to make a single selection from a list of options, making it a valuable tool for any application that requires user input

This code is a Vue.js implementation of a single chip selection drop-down menu. It can be broken down into the following steps:

1. The Vue instance is created with the “el” property set to the “#app” div, which serves as the root element for the Vue application.
2. The “data” property of the Vue instance is defined to return an object that contains the following properties:
   • “items” – an array of options for the drop-down menu
   • “selectedItem” – the default selected option
   • “showDropdown” – a boolean value that determines whether the drop-down menu is visible or not
3. The “methods” property of the Vue instance is defined to return an object that contains the following methods:
   • “toggleDropdown” – toggles the visibility of the drop-down menu
   • “selectItem” – sets the selected option and closes the drop-down menu
   • “remove” – removes the selected option
4. The UI is built using HTML and Vue directives, including v-if, v-show, v-for, and @click.
   • The “chip” div displays the selected option and has a close button for removing the selected option.
   • The “selected-item” div is used to display the selected option and opens the drop-down menu when clicked.
   • The “dropdown-list” ul displays the options in the drop-down menu and updates the selected option when clicked.

<div id="app">
   <div class="chip" v-if="selectedItem">
         {{ selectedItem }}
     <span class="close" @click="remove">x</span>
   </div>
 <div class="dropdown">
    <div class="selected-item" @click="toggleDropdown">{{ selectedItem }}</div>
       <ul class="dropdown-list" v-show="showDropdown">
          <li class="dropdown-item" v-for="item in items" @click="selectItem(item)">{{ item }}</li>
       </ul>
    </div>
 </div>
 <script type="module">
        const app = new Vue({
            el: "#app",
            data() {
                return {
                    items: ['HTML', 'CSS', 'React','Vue','Angular','Node','PHP'],
                    selectedItem: 'CSS',
                    showDropdown: false
                }
            },
            methods: {
                toggleDropdown() {
                    this.showDropdown = !this.showDropdown;
                },
                selectItem(item) {
                    this.selectedItem = item;
                    this.showDropdown = false;
                },
                remove() {
                    this.selectedItem = '';
                }
            }
        });
</script>
