Description
The gform_force_hooks_js_output filter can be used to prevent the Gravity Forms scripts from being injected into the pages if they’re not necessary.
Note: Enabling this filter may cause the server to use more memory. It is recommended that you monitor memory usage if you experience performance issues, particularly in cases where the Dom_Parser class is involved.
Usage
add_filter( 'gform_force_hooks_js_output', 'your_function_name' );
Parameters
Defaults to false. Set to true using the WordPress __return_true function or a custom function that returns true.
Examples
add_filter( 'gform_force_hooks_js_output', '__return_true' );
Placement
This code can be used in the functions.php file of the active theme, a custom functions plugin, a custom add-on, or with a code snippets plugin.
