Paul, thanks for the tip.
I followed your recommendation you gave me on the accordion contribution:
"I will show you using on back-end editor (SPPB 5.0.8) - where it's easier to see all details / settings. Use that editor, save your time."
If I want to make changes in the existing Simple Portfolio page in the back-end editor, I should first export the portfolio page, then import into a new SP Pagebuilder page, make changes, then export again, delete everything in the portfolio page and import again ?
You can't be serious.
regards Josef
