Thanks for your interest! I’m not sure what you want to do. You can put links, images, tables, etc. on flashcards (front and/or back). Using the “code editor” mode in the WordPress Block editor (“text mode” in the Classic editor) — or a plugin — you can put an iframe (that shows external content) on a flashcard. A link can open a page in a new tab, or in the current tab. An automatic redirect? I don’t think that’s available — or why you’d want that to happen.
I want to redirect to internal slides as client added many section so i let se on click i should go to that slide of flashcard, is that possible?
I think what you are asking for is that after the user does a set of flashcards in Qwizcards, they can then click a link to continue with additional flashcards on a new (external?) page. The answer is yes, sure. A handy place to put such a link is in the “exit text” shown when the user completes a flashcard deck. (See https://qwizcards.net/flashcards-quickstart/
