The plugin allows you to add a feedback form or booking form to the page. The data is sent to the server via AJAX (this can be disabled using the settings and the form will be submitted as usual, with a page reload… but why do you need it?). You can flexibly personalize the form and its fields.
The form is added to a page using the Gutenberg Custom Blocks – with these blocks, the possibilities for customizing your form are greatly increased.
You can also add a form to a page using the shortcode <code>[zu-contact]</code> or <code>[zu-booking]</code>.
