I have implemented a couple of rich text input schemes feeding collections on sites I have worked on and been forced to use CKEditor to make it work. The process of getting CKEditor to work well, using a little JavaScript is not all that hard but is poorly documented and the final rich text on screen during input is not rendered in CKEditor in the same way as it is on Wix, when the rich text is displayed in a text field.
Is this feature planned? It‘s been on the standard editor for a couple of years now…it’s time to bring it to your premium platform too.
