Can a form submit button have an ID attribute?

Hi [@Annie\_Birai](https://community.hubspot.com/u/annie_birai),

To clarify, do you wish to set a form submit button’s HTML [id](https://www.w3schools.com/tags/att_id.asp) attribute by [customizing the embed code](https://developers.hubspot.com/docs/methods/forms/advanced_form_options)?

If so, this is not possible, but you can set the button’s class with `submitButtonClass`.
