Initialize Action Form

Audience: Low-code Engineers
Skill Prerequisites: HTML

This action allows you to manually trigger the initialization of a Form.

It is helpful in situations where you have multiple Form modules on the same page, and you set their Display Mode to Manual. This prevents the forms from loading and helps save bandwidth at page load (your page will load a lot faster) while allowing you to initialize them (wake them up) when they are needed.


The page will not be refreshed when a Form is initialized.
