Hi there,
You can align the buttons (radio field) vertically using custom CSS codes. Here is an example code snippet –
.fluentform .ff-el-group.ff_list_buttons .ff-el-form-check {
display: block;
}
.fluentform .ff-el-group.ff_list_buttons .ff-el-form-check label>span {
border-left: 1px solid #dcdfe6;
}
.fluentform .ff-el-group.ff_list_buttons .ff-el-form-check:first-child label>span,
.fluentform .ff-el-group.ff_list_buttons .ff-el-form-check:last-child label>span {
border-radius: 4px;
}
You can add that in the custom CSS section of your form. You can do further customization as you need using CSS codes.
Thank you.
