Install
No release zip yet. The repository archive installs, but the folder name will carry the branch suffix and updates will not flow:
wp plugin install https://github.com/zodiac1978/html5-fallback-wpcf7/archive/refs/heads/master.zipReadme
html5-fallback-wpcf7
A simple plugin if you want to use the date or number input fields and wish to use a localized jQuery UI-based fallback feature in Contact Form 7.
What does it do?
Basically it just adds this line add_filter( 'wpcf7_support_html5_fallback', '__return_true' ); which could also be in a functions.php of a child theme. But if you don't have a child theme, then this plugin is quite handy.

Additionally it localizes this datepicker field for all the languages that are avalaible for localization from the jQuery UI website (https://github.com/jquery/jquery-ui/tree/master/ui/i18n).
