I would like to use an inline badge with v3, but there is no documentation on badge position for v3.
EDIT1: See the answer using the render=explicit parameters. This answer still works but it was before this feature was documented and not as clean.
I've managed to do just that by placing a relative box and detaching the reCaptcha v3 badge into it. Then some style adjustments are made to the container.
#grecaptcha-box {
width: 260px;
overflow: hidden;
position: relative;
height: 75px;
}
#grecaptcha-box .grecaptcha-badge {
box-shadow: none !important;
}
Then you place the box followed by your JavaScript.
