Clean-up Yii form validation errors after creation

Hey!
Im working on a project and it uses ActiveForm validations to warn about errors to the user, while that part is working ok, i have elements which can be dynamically added or removed, and when i removed an element which had an errored field, it doesn’t clean up.
I managed to partially clean this up by removing the “error” class using jquery on PHP, but i need to hide the em (error message) fields once again, how can i do that with ease?

The code im using to clean up the error class:

        row.find("div").each(function() {
            let currentDiv = $(this);
            let input = currentDiv.children("select, input");

            input.each(function(){
                $(this).val('');
            });

            if (index > 1) {
                if(currentDiv.hasClass("product_code") || currentDiv.hasClass("description")){
                    if (currentDiv.children("input").data("ui-autocomplete")) {
                        currentDiv.children("input").autocomplete("destroy");
                    }
                }
                if(currentDiv.hasClass("error")){
                    currentDiv.removeClass('error')
                }
            }
        });

And this is the code which adds and removes more fields/rows, the code in which the snippet above is called is inside the remove one, named resetValueEstimationRow(row)

function addNewValueEstimationRow(){
        let row = $(document.querySelector('#value-estimation-fieldset > .hidden-item-row'));
        let codeAutoCompleteOptions = $("#ExceptionClassification_product_code_0").autocomplete("option");
        let productAutoCompleteOptions = $("#ExceptionClassification_description_0").autocomplete("option");
        row.removeClass("hidden-item-row");
        // add autocomplete
        row.find(".classification-loss>div").each(function(index){
            let currentDiv = $(this);
            let input = currentDiv.children("input, select");

            if (currentDiv.hasClass("product_code")) {
                input.autocomplete(codeAutoCompleteOptions);
            } else if (currentDiv.hasClass("description")) {
                input.autocomplete(productAutoCompleteOptions);
            }
        });

        // Limit
        let numberOfRows = $("#value-estimation-fieldset .classification-item-row:not(.hidden-item-row)").size();
        $("#addNewEstimationValueButton").attr("disabled", numberOfRows >= <?= ExceptionClassification::MAX_ITEMS ?>);
    }

    function removeValueEstimationRow(event){
        let numberOfRows = $("#value-estimation-fieldset .classification-item-row:not(.hidden-item-row)").size();
        if (numberOfRows < 2) {
            console.error("Can't remove value estimation last row");
            return false;
        }
        let div = $(event.target.closest("div"));
        let row = div.parent();
        resetValueEstimationRow(row);
        //Remove autocomplete
        div.children(".product_code>input, .description>input").autocomplete( "destroy" );
        $("#addNewEstimationValueButton").attr("disabled", (numberOfRows - 1) >= <?= ExceptionClassification::MAX_ITEMS ?>);
    }

How do i get the div with (“em”) in its id so i can hide it again in this case?
