Hi, I used Easy Modal plugin to solve this problem – https://www.ads-software.com/plugins/easy-modal/

Install Easy Modal plugin, use the editor to insert content into your modal.

Follow the instructions to obtain the class id of your modal, then add the class to the link, button or image link where you want the modal to pop up.

quick-tip: if you use this plugin, be sure to set ‘display modal sitewide’ to yes, Myself and some other users had to do this to make the plugin work.

if you need any more help post here or on the Easy Modal support forum.
