I made template with lists and paragraph styles. But I can’t delete some styles at all, such as Title 1, Title 2 and so on. Those styles have no such ability in context menu and have no reaction on “Delete” button.
The default styles in LibO can not be deleted at all. You only can change them.
I highly recommend to read a bit about the styles; see also my answer at:
Why, “can not be deleted”? What’s logic here? Why unused styles can’t be deleted? Why it’s restricted?
I assume that these default styles are needed to do anything. If they are gone, you might be lost.
I was at the beginning about to delete all default styles and set up my own styles. But, I changed my approach and modify the default styles that they suit me, and add additional styles when I need them on top of the modified default styles. To me this is the best approach. Maybe you can do the same.
I started using LibO 5 month ago and use only LibO…
I also hope that one of the experts here will give you a better explanation on the reason why default styles cannot be deleted.
