HTML tag inside contact form7 NOT getting sent over an email

FAQ > Nothing shows up in the email, even after adding a tag to the form! How can I include a new field’s input in the email?

I have already included the tag but it still does not work.
The only difference is the tag is not of contact form7 ([select])
but it is plain HTML <select> .

Please note it works for other HTML selements like <input type=”text”/”textarea” etc but NOT for <select> .
wondering why so.

Also, the link : https://contactform7.com/styling-contact-form/

talks about styling the basic components and not select/dropdowns.
for me, following css snippet is making NO difference:

.wpcf7 select{
height:30px;width:200px
}
