A submit button is an essential component of a form. As you may know, HTML represents a submit button as an input element with
<input type="submit">. You can use this HTML tag in a contact form of Contact Form 7, but you should use Contact Form 7’s own
submit form-tag instead.
This is the simplest form of submit tag:
You can add a value like this:
[submit "Send Mail"]
Did you notice that the submit tag’s syntax is bit different than other form-tags? The submit tag does not have name part, which other form tags have.
In addition to this, you can add several options to submit tag.
[submit class:button id:form-submit "Send Mail"]
