We upgraded our app from v5 to v6, we have a page where we are displaying expandable items and we thought we would make use of the newly introduced ion-accordion, the problem is on page load all the items are collapsed, I want the first item expanded while all the other items are closed. Are there any attributes I can set on ion-accordion to achieve this?

After going through the official documentation I just found that you can have an item expanded by default using the value attribute on ion-accordion-group tag.
<ion-accordion-group value="colors"><ion-accordion value="colors"><ion-item slot="header"><ion-label>Colors</ion-label></ion-item><ion-list slot="content"><ion-item><ion-label>Red</ion-label></ion-item><ion-item><ion-label>Green</ion-label></ion-item><ion-item><ion-label>Blue</ion-label></ion-item></ion-list></ion-accordion></ion-accordion-group>Note the value in ion-accordion is equal to that in ion-accordion-group.
if you set the value for with the name of the accordion the default will be the mentioned accordion Expanded
<!-- Multiple Accordions --><ion-accordion-group [multiple]="true" [value]="['colors', 'numbers']"><ion-accordion value="colors"><ion-item slot="header"><ion-label>Colors</ion-label></ion-item><ion-list slot="content"><ion-item><ion-label>Red</ion-label></ion-item><ion-item><ion-label>Green</ion-label></ion-item><ion-item><ion-label>Blue</ion-label></ion-item></ion-list></ion-accordion><ion-accordion value="numbers"><ion-item slot="header"><ion-label>Numbers</ion-label></ion-item><ion-list slot="content"><ion-item><ion-label>one</ion-label></ion-item><ion-item><ion-label>two</ion-label></ion-item><ion-item><ion-label>three</ion-label></ion-item></ion-list></ion-accordion></ion-accordion-group>in this case Accordion "Colors" and "Numbers" are Expanded.if you want only the first one delete numbers from [value]="['colors', 'numbers']"
