If you do not find something (a needed feature) in the addon settings, you can change it by going to Addon php code customization. To prevent the changes made in the addon file(s) from being overwritten when updating the component, we suggest using the following method. 

1. Create those folders inside your template folder:  templates\shaper_NAME\sppagebuilder\addons\
"shaper_NAME"  is just an example, you have to use your real template folder name. It can be: shaper_helixultimate,  shaper_doctor or even cassiopeia etc.

2. Then inside newly created folders copy the addon folder, for example:
   

   templates\shaper_NAME\sppagebuilder\addons\button_group

   inside must be site.php or/and admin.php file that you want to customize (add changes).

3. Then Joomla will use those files before using the addon from a component folder. It means that you can update the SP Page Builder in the long term and your customization will be used.
