In a radio field, can I add a text box after each radio to collect more information?

As far as I know, we do no have a feature like that, but you could somehow accomplish this by injecting custom CSS code:

#input_17 {

position:absolute;

margin-top: -118px;

margin-left: 240px;

}

#input_18 {

position:absolute;

margin-top: -105px;

margin-left: 300px;

}

#input_19 {

position:absolute;

margin-top: -95px;

margin-left: 220px;

}

#input_16 {

position:absolute;

margin-top: -83px;

margin-left: 170px;

}

.form-label-top{

display: none;

}

In addition to what my colleague has stated, you can shrink the text box fields and create conditions to show each of them only when the relevant radio button is selected, as in this demo. Feel free to clone it and examine its conditions.

Thanks, this is very helpful. Is there a source code editor in my account that I can add additional code to the existing form?
