number the questions

I'm not sure if I could understood completely your question, but as I can understand you want to add a number to the questions you have in your form, if this is correct then you could inject this code:

ul {

    counter-reset: item;

    list-style-type: decimal;

}

li.form-line:not([data-type="control_button"]):before {

    content: counter(item, decimal);

    counter-increment: item;

    margin-left: -15px;

    top: 12px;

    position: absolute;

}
