Hi All, I am working on SignUp form. I have bunch of checkboxes which users are supposed to check and then i need to save them in the database. For this, I have created a hidden variable which will contain the values of selected checkboxes and send them to api. I wrote this code inside a JS function. Now, Issue is that I am not able to Call the JS function on any event. I want to call the function on continue button click. Does anyone knows how to do this? ---

Hi @msharma Welcome to the Auth0 Community! If you are looking to add checkboxes for your signup scree, I would recommend [customizing the signup prompts using partials](https://auth0.com/docs/customize/login-pages/universal-login/customize-signup-and-login-prompts). By using partials, you will be able to capture and set the data using a [Post-User Registration Action](https://auth0.com/docs/customize/login-pages/universal-login/customize-signup-and-login-prompts#validate-and-save-captured-data) as seen in the example linked in the documentation. Otherwise, if you are using Auth0 Forms to implement custom signup elements, I would recommend using a Flow to bind the necessary information to the user. If I am not understanding your implementation correctly, please provide me some examples of how are you trying to implement this functionality. I will be looking forward to your other questions on the matter! Kind Regards, Nik ---
