Checking the checkbox can make the page jump.

I don't know all the details here, but when I dynamically add checkradio buttons to the page and then click on them, the entire page jumps partially out of the viewport.

I was able to stop this from happening by changing the input for the checkradio to have display: none

You don't need to see the checkbox anyway, so this seems like the way it should be anyway.

Hi,

have you checked if display: none is set then the input value is sent when submitting the form ?
My (poor) memory tells me this choice was related to the form submit behavior.

Ah, that's true. I'll check. I'm currently using the checkboxes for interaction rather than form submission. Maybe it would work to use visibility:hidden and position:absolute instead...
