Core Concepts You Should Know
Let’s break down the basics.
1. x-data – Your Component State
This defines your data.
👉 Here:
open is a variable- We toggle it on button click
- Content shows/hides based on it
2. x-show – Show/Hide Elements
Works like display: none but controlled by data.
3. @click – Handle Events
This updates the state instantly.
4. x-bind – Bind Attributes
Dynamically change classes or attributes.
5. x-model – Two-Way Binding
👉 Whatever you type updates instantly.
