Webviewer as Multiline Text Input

Hi thunkers. one of my concern is multiline text input
But as far as we know, when user type in text input (set multiline) and press enter, the keyboard, user can input next line but keyboard will be dismissed immediately.

it bothers me, so i think webviewer as text input.
to user, it looks just same as other text input.
and when user click confirm button, then webviewer give me the data

how is that? you guys think it works?

Can you also mention how you made this

i didn’t try. actually im not familiar to HTML, although i have a website made of wordpress.

just want to ask you guys
