Remove Required Text
You can remove the required fields text by adding a blank space to the “FIELDS MARKED WITH AN * ARE REQUIRED” input under Advanced Settings in the form builder. Go to Advanced > Display Settings and under the specific required text you want to hide, add a single blank space and save the settings.
You can also rename the text “Fields marked with an * are required” from this area.

Hide Required Text
You can also hide the “Fields marked with an * are required” area from showing on your form using the following CSS:
.nf-form-fields-required {
display: none;
}Translate “Fields marked with an * are required”
There are several pieces of text that are output on the form that are not specifically related to the fields you add to your form. These are important strings because they provide feedback for those filling out the forms, but on occasion, you may want to change those values.
Below is an example of the code you can add to your functions.php file in order to translate the “Fields marked with an * are required” text.
If you don’t know how to access your function.php file using WordPress, navigate to your WordPress site to Appearance > Theme Editor. You can also access the function.php file using FTP.
The example of the code provided below uses the Polish language. No changes in the code are necessary. You place it as is, and replace only the text stringPolja označena * su obavezna with your own translation.
<?php
add_filter( 'ninja_forms_i18n_front_end', 'my_custom_ninja_forms_i18n_front_end' );
function my_custom_ninja_forms_i18n_front_end( $strings ) {
$strings['fieldsMarkedRequired'] = 'Polja označena * su obavezna';
return $strings;
}
