Model, or custom, tags are the tags that reference your custom script data. These tags can take on any form you choose, and can reference a variety of options and their unique values.
When you add a new element to your script, like a Checkboxes or Table element, that element will, by default, generate a custom tag that you can report on and/or refer to later in the script. Please note that only elements that allow for some type of data-capturing (whether via a clicked selection or a text/character input) can generate model tags by default.
Say you add a Radio Buttons element to your script that offers three options — yes, no, and maybe — and you name that element ‘Choices.’ You’ll immediately be able to use that ‘Choices’ element (or any of its results) anywhere else you like within the script by referring to the tag that is automatically created once you give your Radio Buttons element a Field Name.
Please note that when you access Available Data - Tagging settings, the generated custom tag that appears in the list takes its name from whatever you enter into the Input Label field. The element type is listed beside this, and to the far right you’ll see the name you entered into the Field Name setting.
