If you prefer not to create a new component each time, but want your main menu to appear in multiple locations, you can utilize the ref="menu" attribute to access its content through innerHTML or outerHTML. An example demonstrating this can be found here.
<div id="app">
<main-menu ref="menu" />
<div v-html="menuHTML"></div>
</div>
It's important to note that refs are not reactive, so attempting to use
v-html="$refs.menu.$el.outerHTML"
directly may lead to errors. To properly display the menu's content, you need to initialize it in the
mounted hook:
data() {
return {
menuHTML: ''
}
},
mounted() {
this.menuHTML = this.$refs.menu.$el.outerHTML;
}
This approach allows for displaying the menu in various places without creating new components, although it lacks reactivity.
In the provided example, menu items are stored in an items array. Any changes made to objects within this array will affect the main component but not its clones. For instance, I demonstrate adding the "red" class to items after a delay of two seconds.
To ensure changes reflect on cloned elements as well, you should set up a watcher to monitor modifications in the items array and update the menuHTML accordingly:
mounted() {
this.menuHTML = this.$refs.menu.$el.outerHTML;
this.$watch(
() => {
return this.$refs.menu.items
},
(val) => {
this.menuHTML = this.$refs.menu.$el.outerHTML;
}, {
deep: true
}
)
}
You can also keep track of changes in any data property using:
this.$refs.menu._data
By following this method, you can avoid passing props to the main menu component or making alterations to it directly. However, implementing additional logic in the parent component is necessary for this solution to work effectively.
