For all new installations of Ninja Forms 3.4.11 and later (7 May 2019), certain advanced features of the form builder are disabled by default. This was a decision made to improve user experience through reducing the clutter of more niche options in the form builder. Enabling Developer Mode will “unhide” these features.
Enabling Developer Mode
- Navigate to Ninja Forms > Settings in your WordPress dashboard
- Scroll down to the Advanced Settings section
- Check Form Builder “Dev Mode”
All features flagged as advanced Developer Mode features will now be present in your form builder.
