What is the best way to collapse all expansion panels at once?

Question

What is the best way to collapse all expansion panels at once?

I need to close my expansion panel automatically when I click on the Update button.

Is there a way to achieve this programmatically?

This is the content of my update() function:

update(index) {
  console.log("index", index);

  let vehicle = {};
  vehicle.VIN = this.savedVehicles[index].VIN;
  vehicle.ModelYear = this.savedVehicles[index].ModelYear;
  vehicle.Make = this.savedVehicles[index].Make;
  vehicle.Model = this.savedVehicles[index].Model;

  this.savedVehicles[index] = vehicle;
  localStorage.setItem("savedVehicles", JSON.stringify(this.savedVehicles));

  this.alert = true;
  this.alertColor = "green";
  this.alertMessage = `${vehicle.VIN} updated`;

  // hopefully collapse all expansion panels 👈🏽👈🏽👈🏽

},

Answer №1

External control of expansion panels can be achieved by adjusting the v-model attribute. This value corresponds to the zero-based index of the currently expanded panel content. If multiple properties are utilized, it becomes an array that contains the indices of the open items.

If you only need to control a single expansion panel, use this method:

<template>
  <v-expansion-panels v-model="panel">
     // add your code here
  </v-expansion-panels>
  <button @click="closePanel()">Close</button>
</template>
<script>
export default {
  data() {
    return {
      panel: 0 // This means the panel should open by default
    }
  },
  methods: {
    closePanel() {
      this.panel = null; // Setting to null will close the panel
    }
  }
}
</script>
