Hello There,
Thanks for writing in!
Which code you are referring to?
#1
jQuery('.services select > option:first').addClass('hidden');
jQuery('.budget-range select > option:first').addClass('hidden');
jQuery( ".hidden" ).prop( "disabled", true );
#2
//
// No need to add script tags
// here; simply get started
// by writing JavaScript!
// Remember to save your
// changes to see them :)
//
jQuery("#modal-form-submit").after("<span></span>");
jQuery('.services select > option:first').addClass('hidden');
jQuery('.budget-range select > option:first').addClass('hidden');
jQuery( ".hidden" ).prop( "disabled", true );
jQuery(".services-link").wrap("<a href='services-2'></a>");
The #1 can be removed or change in the theme options custom js section (http://prntscr.com/evswzb) or in the customizer, Appearance > Customize > Custom > Edit GLOBAL Javascript
The #2 can be change in Cornerstone custom js section, Custom JS
Hope this helps.
