Customizing the appearance of your fields using CSS is a common task in JotForm. If you need to change the CSS properties for a specific field, knowing the ID of the field allows you to target that specific field.
The Unique Name of the field on the other side is used to reference the value of a field in other places such as in a different question, in the email body, passing the field’s value as a URL parameter, etc.
Follow the steps below to get the ID or the Unique Name of a field:
- In the form builder, select a field and click its gear icon to open the properties window.
- Go to the Advanced tab.
- Scroll down to the bottom and click to expand the Field Details.
- A small section will open up where you can see the Unique Name and Field ID.
Note that not all form elements have the Field Details section. In these cases, you can extract the Unique Name or get the field ID using your browser’s developer tool.
