Theme Horse

Hi claude,
First of all create a child theme. And under it create a two files style.css and function.php.In functions.php of the child theme, create your widgets and register them. Just copy the parent widget, change the name of widget like Theme Horse Child: Featured Page Widget, make customisation and create your custom widget. If you do this, the widgets of parent theme and child both will appear. Use your custom widget of child theme instead of the parent theme.

Just making same file structure in the child theme like /library/widgets won’t overwrite the parent file.
Hope this helps.

If you are still unable to customize the code then you need to hire a developer to fix it.

Thank you!
