Hi @savi50

Please try this.

//rtemaxvalidation.js

(function($, window, document) {
    var registry = $(window).adaptTo("foundation-registry");
    registry.register("foundation.validation.validator", {
        selector: "[data-validation=rtemaxlenvalidation]",
        validate: function(el) {
            var element = $(el);
            var maxLen = element.data('maxlength');
            var rteLen = element.text().trim().length;
            if (rteLen > maxLen) {
               return "Exceeded Maximum Limit";
            }
        }
    });
})
($, window, document);
