Using the “Custom HTML” block, it is possible to embed forms from cryptpad.fr <iframe width=”100%” height=”800px” src=”https://cryptpad.fr/form/#/2/form/view/aaHjngSj9puw7d-lQzl5MaS5VButmClnAabRhWiRfjM/embed/”></iframe> The default CryptPad iframe code might result in a very small window. Manually add the “width=”100%” height=”800px” parameters at the beginning of the iframe tag and adjust them manually to obtain the best result!
