he use of the x-ref directive in Alpine.js plays a key role in managing interactions between nested components and providing access to specific element references within JavaScript expressions. Let's break down the concept of x-ref and its application in your context.
What is x-ref?
x-ref is an Alpine.js directive used to create a reference to a DOM element within an Alpine.js component. Once an element is tagged with an x-ref, you can access it anywhere within the same component using this.$refs, allowing you to manipulate or retrieve data from the element directly.
