Conditional Logic: Showing & Hiding Fields

Modified on Mon, 10 Aug at 4:14 PM

Conditional logic lets your form react to what a visitor types. You can reveal an extra field only when it’s relevant, or hide one that doesn’t apply — keeping the form short and tidy while still gathering the detail you need. For example: only show a “Which product?” field once the visitor has told you they’re a returning customer.

How a rule is built

Each rule reads like a sentence:

If [a field] [meets a condition] [value], then Show / Hide [a custom field].

To add one, scroll to the Conditional Logic section on the form’s edit screen and click + Add Rule. You’ll get a row with these parts:

Part	What to choose
Field (the trigger)	The field whose answer you’re watching. This can be any field — one of the four standard fields or any custom field.
Condition	How to test the answer (see the conditions below).
Value	The text you’re testing against. (Not needed for the “Is answered” condition — the box disappears when you choose it.)
Action	Show or Hide the target field when the condition is met.
Target field	The field to show or hide. This must be a custom field that you’ve included on the form.

The available conditions

Condition	Meaning
Equals	The answer exactly matches the value you entered.
NotEquals	The answer is anything other than the value you entered.
IsAnswered	The visitor has typed something in the field (any value). No comparison value needed.
Contains	The answer includes the text you entered somewhere within it.

Conditions ignore capital letters, so “Yes”, “yes” and “YES” are all treated the same.

Show vs Hide — how they behave

Show — the target field starts hidden and only appears once the condition is met. Use this to reveal an extra field when it becomes relevant.
Hide — the target field starts visible and disappears once the condition is met. Use this to remove a field that no longer applies.

Fields update instantly as the visitor types or makes a choice — there’s no need to reload the page. If a field is hidden at the moment the visitor submits, its answer is not sent and it won’t block submission even if it was marked required.

Tip: You can add several rules. If two rules point at the same target field and one says Show while another says Hide, Hide wins whenever its condition is met — so a field will only stay visible when nothing is telling it to hide.

A worked example

Say you have a custom field called Preferred callback time and you only want to ask for it when the visitor has entered a phone number in a custom Phone field:

If field = Phone
condition = Is answered
Action = Show
Target field = Preferred callback time

Now “Preferred callback time” stays out of sight until the visitor fills in their phone number.

Remember: only custom fields can be shown or hidden. The four standard fields (Your Name, Your Email, Lead Name, Lead Description) are always visible and can be used as triggers but not as targets.
