On click external link open first accordion

I have created two external links and two section containing accordion in each. When I click on Link it scroll to its particular section. I am trying to open its first accordion on Link click.

$(document).ready(function(){
// Add smooth scrolling to all links
$(".explore-card a").on('click', function(event) {
// Make sure this.hash has a value before overriding default behavior
if (this.hash !== "") {
// Prevent default anchor click behavior
event.preventDefault();
// Store hash
var hash = this.hash;
// Using jQuery's animate() method to add smooth page scroll
// The optional number (800) specifies the number of milliseconds it takes to scroll to the specified area
$('html, body').animate({
scrollTop: $(hash).offset().top
}, 800, function(){
// Add hash (#) to URL when done scrolling (default click behavior)
window.location.hash = hash;
});
} // End if
});
});

I am trying to open its first accordion on external Link click.

Adding these attributes to the first link will do it:

data-toggle="collapse" data-target="#a1"

After adding it will look like this:

<a href="#Segment1" class="explore-link" data-toggle="collapse" data-target="#a1">
