Password: abc
Description: Hover on each button > Show the corresponding Summary Block.
#1. First, you add 2 Button Blocks with some text/url.
Make sure the option “Open link in new tab” is disabled
- #summary01
- #summary02


and 2 Summary Blocks below.

#2. Install Squarespace ID Finder to find the ID of the Summary Block.
In my example, we will have:
- Left Summary Block: #block-yui_3_17_2_1_1715307967768_21203
- Right Summary Block: #block-yui_3_17_2_1_1715307967768_26779

#3. Use code to Code Injection – Footer (or Page Header Code Injection)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.7.0/jquery.min.js"></script>
<script>
$(document).ready(function(){
// Summary 01
$("#block-yui_3_17_2_1_1715307967768_21203").closest('.fe-block').addClass('summary01 show');
$('a[href="#summary01"]').addClass('active-button');
// Summary 02
$("#block-yui_3_17_2_1_1715307967768_26779").closest('.fe-block').addClass('summary02');
// Summary 01
$('a[href="#summary01"]').hover(function(){
$(".summary01").addClass("show");
$('.fe-block:not(.summary01)').removeClass('show');
$(this).addClass('active-button');
$('a:not([href="#summary01"])').removeClass('active-button');
}
);
// Summary 02
$('a[href="#summary02"]').hover(function(){
$(".summary02").addClass("show");
$('.fe-block:not(.summary02)').removeClass('show');
$(this).addClass('active-button');
$('a:not([href="#summary02"])').removeClass('active-button')
}
);
});
</script>
<style>
.summary01 .summary-v2-block, .summary02 .summary-v2-block {
display: none;
}
.show .summary-v2-block {
display: block !important;
}
.show {
z-index: 999999 !important;
}
.active-button {
background-color: green !important;
}
</style>
