LibreOffice 24.8 Help
Shows or hides hidden paragraphs. This option only affects the screen display of hidden paragraphs, and not the printing of hidden paragraphs.
To enable this feature, choose - LibreOffice Writer - View, and ensure that the Hidden paragraphs check box in the Display fields area is selected.
Use the field command "Hidden Paragraph" to assign a condition that must be met to hide a paragraph. If the condition is not met, the paragraph is displayed.
When you hide a paragraph, footnotes and frames that are anchored to characters in the paragraph are also hidden.
