Hi Ananya, not without changing the component itself. I would guess that using built in accordion would be a more natural fit for your use case.
If you want to proceed with this one, you should clone the component and create a JS inside a client action that would toggle the CSS class is-open on all rows or that would programmatically click on the table rows. But again, it doesn't seem to me that this would be a good use of this component, as it differs from its initial intent and architecture.
