Adjust the lightbox height and remove the vertical and horizontal scrolling

On another note, is there a piece of code I can use to expand the width of the lightbox to accommodate the vertical scrollbar and remove the need for horizontal scrolling on PC after the radio button is clicked?

In your form embed codes, you can adjust the width and height value. For example:

You can remove the horizontal scroll by adding the following custom CSS codes in your current web page:

<style>

.jt-content {

    overflow-x: hidden !important;

}

</style>

Add these above or below the form embed codes.

I won't recommend removing the vertical scrolling because the height of the form won't fit in the PC screen when the address field is shown.

Thanks
