I’m auditioning your plugin and it looks simple and easy to use. Unfortunately that is a problem.

I click on the element button, then on the group of elements I want to add, but when the list opens the only button I see is the “cancel” button, no “insert” button. That is a problem.

I await the next update.

Though the plugin ‘WP Sitebuilder’ is in beta version, it is continuously updating.
Feel free to ask any query if you have or ask for support or ‘How to’s. Your are welcome. We will try to respond and help asap.
