I wanted to store few 100 paragraphs in the app. I will use each paragraph as list items. Is it possible to store them together in one place instead of using 100s of list blocks?
Too many list blocks will overwhelm the Blocks Editor.
You could make each paragraph a text file in the Media folder, and a list of their file names in a separate index file, also in the Media folder.
Be sure to reuse the same File and Label components. You don't need or want 100 of them.
....you should be able to store them in TinyDB, each paragraph under it's own tag, carefully named for ease of recall.
