Hi there,
Please check accordion element as you may find this useful : http://demo.theme.co/integrity-1/shortcodes/accordion/
If you want to add a button to show and hide the content, please add a raw content element and insert following code :
<button class="btn">Click here</button>
<div class="custom-div">text goes here</div>
Please add following code in Customize -> Custom -> JavaScript :
jQuery("button.btn").click(function( ){
jQuery(".custom-div").toggle();
});
Hope that helps.
