To get you started
Start phpmyadmin and look at the pages and sections tables, for starters look at the wysiwyg
then add a page with a wysiwyg section
See what is added to the tables with phpmyadmin, look at other tables as well to see what is happening when you add a page
Then.... start coding
Other way to look at stuff,
take a look at the code wich adds a page and look at the code wich adds a wysiwyg section
Taking these two codes start your way from there
To speed things up, use a local xampp installation so you won't mess up a public install
The nice thing about WB is you can code whatever you want, but you need to code the odd things you can use as one of the few.
If this was helpfull for many then someone (even me) could start coding it.
Learn to code, you can't harm a local test-install
You can allways ask in the forum for some help if you can't get it to work.
