All standard WordPress Pages, Citadela Pro special pages and Citadela Listing special pages include Citadela Page Settings metabox where are available options to remove default page title section. Feature may be useful when you decide to not use standard page title designed by theme. For example if you would like to show other type of content right below the header using Gutenberg editor (ie. Cover image, Slider or anything else available via Gutenberg editor).
Do not miss the Page Title block included in Citadela Blocks plugin which can be used to move standard theme title section anywhere in page content using Gutenberg Editor. Find more information in Citadela Blocks Plugin documentation.
