Hey Everyone, Anyone got an idea on how I can validate a big custom form? Is there a component for validating a custom form that is this big? You can see all the fields in the table bellow. I need to use a custom field because there are some parts of the form (e.g. visability rules and ‘confirm password’) functionality that need to be there. ![Screen Shot 2022-07-04 at 4.57.28 pm](https://us1.discourse-cdn.com/flex020/uploads/adalo/original/3X/b/f/bf8da22563eb7d86d5bd41012f53c5f412ee9079.png) Yes it just best if I split this whole thing up? I would like to avoid this if possible. ---

The way I’m validating custom forms is with visibility conditions in the submit button. Set the first visibility condition → group → set the second visibility condition → group → and so on… The visibility conditions are linked to the mandatory fields you have in your custom form. In certain cases, I do have the forms split into two, where it makes sense to do so, where the second part of the form is a pop-up with optional fields. ---

But does this guarantee full validation? And 100% bring the button back? Thanks, Archer Simmonds ---

Yes. It works for me. Just ensure you don’t miss any of the visibility conditions and that everything is set up correctly and you are good to go. ---

Check out this video by Pragmaflow: [Tutorial - Adding validation to custom forms - YouTube](https://www.youtube.com/watch?v=IsqfoiTalgI) It uses javascript to validate the form fields. I’ve done this for a few forms. Works really well. ---
