Hi ELise,
Thanks for reply
As for gaps I don’t know what adds them. I upload all product data by excel. I don’t know why they appear. And only in description. I’ll contact Wp All Import for it

About that Auto-Collapse the code is not working It gave me error and didn’t work. Frpleaced that error with correction they gave me and gane me a new one, replaced it and gave a third
Please check image and advice

Thanks
