Hi We developed our in house theme using your tool suite and we've come across a big limitation! The page builder got extremely slow to the point where it's actually not usable not even for us! I can send you a snap of our meta boxes if necessary but the file is 800 lines long! Please help us fix this issue as we cannot proceed further on the client's website using this pattern! If you have a solution, please help us! hank you very much!
The clone feature uses jQuery and when a clone event is fired, it loops through all the inputs, updating their indexes, values and name attribute. The more inputs, the longer the process take.
I have improved the speed of cloning in this ticket. I'd suggest you reduce the number of inputs and use the wysiwyg field for some cases. Here is an interesting discussion about this.
