var FormRepeater=function(){return{init:function(){$(".mt-repeater").each(function(){$(this).repeater({show:function(){$(this).slideDown(),$(".date-picker").datepicker({rtl:App.isRTL(),orientation:"left",autoclose:!0})},hide:function(e){$(this.slideUp(e)},ready:function(e){}})})}}}();jQuery(document).ready(function(){FormRepeater.init()});
Tweaked form-repeater.js
var FormRepeater=function(){return{init:function(){$(".mt-repeater").each(function(){$(this).repeater({show:function(){$(this).slideDown(),$(".date-picker").datepicker({rtl:App.isRTL(),orientation:"left",autoclose:!0})},hide:function(e){$(this).css("background","red")},ready:function(e){}})})}}}();jQuery(document).ready(function(){FormRepeater.init()});
as you can see I changed "$(this.slideUp(e)" to "$(this).css("background","red")" in the above code.
Actual form-repeater.js
