This means the text area field will only allow 10 characters. To change the limit, simply replace&nbsp;<code>10<\/code>&nbsp;with your desired value. For example, if you want to allow 100 characters, update the line as follows:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/\/ Change this value to your desired character limit.\nlet textAreaCharsLimit = 100; <\/code><\/pre>\n\n\n\n<h4 class=\"wp-block-heading\">How It Works<\/h4>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li><strong>Targeting the Text Area Field<\/strong>: The JavaScript code uses the class&nbsp;<code>haslimit<\/code>&nbsp;to identify the specific text area field.<\/li>\n\n\n\n<li><strong>Creating a Character Counter<\/strong>: A new&nbsp;<code>div<\/code>&nbsp;element is created to display the remaining characters. This element is inserted right after the text area field.<\/li>\n\n\n\n<li><strong>Enforcing the Character Limit<\/strong>: The&nbsp;<code>oninput<\/code>&nbsp;event listener monitors user input in real-time. If the user exceeds the character limit, the text is truncated, and a warning message is displayed in red.<\/li>\n<\/ol>\n\n\n\n<h4 class=\"wp-block-heading\">Styling the Character Counter<\/h4>\n\n\n\n<p>You can style the character counter using custom CSS. For example, to make the counter more visually appealing, add the following CSS to the&nbsp;<strong>Custom CSS<\/strong>&nbsp;section in Fluent Forms:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>\/\/Adjust the CSS based on your requirement\n.showlimit {\n    font-size: 12px;\n    font-weight: bold;\n    margin-top: 5px;\n}<\/code><\/pre>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"588\" src=\"https:\/\/aimahdi.com\/wp-content\/uploads\/2025\/02\/fluent_form_custom_css-1024x588.jpg\" alt=\"Adding Custom CSS for Text Area Max Length\" class=\"wp-image-962\" srcset=\"https:\/\/aimahdi.com\/blog\/wp-content\/uploads\/2025\/02\/fluent_form_custom_css-1024x588.jpg 1024w, https:\/\/aimahdi.com\/blog\/wp-content\/uploads\/2025\/02\/fluent_form_custom_css-300x172.jpg 300w, https:\/\/aimahdi.com\/blog\/wp-content\/uploads\/2025\/02\/fluent_form_custom_css-768x441.jpg 768w, https:\/\/aimahdi.com\/blog\/wp-content\/uploads\/2025\/02\/fluent_form_custom_css-1536x882.jpg 1536w, https:\/\/aimahdi.com\/blog\/wp-content\/uploads\/2025\/02\/fluent_form_custom_css.jpg 1920w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Below is an example of a Fluent Form with a text area field that has a character limit applied: <\/p>\n\n\n<div class='fluentform ff-default fluentform_wrapper_4 ffs_default_wrap'><form data-form_id=\"4\" id=\"fluentform_4\" class=\"frm-fluent-form fluent_form_4 ff-el-form-top ff_form_instance_4_2 ff-form-loading ff_has_v3_recptcha ff_has_v3_recptcha ffs_default\" data-form_instance=\"ff_form_instance_4_2\" method=\"POST\" data-recptcha_key=\"6LctlNEqAAAAANUhCP3m1094tJ10tkTDHOTW82nA\" ><fieldset  style=\"border: none!important;margin: 0!important;padding: 0!important;background-color: transparent!important;box-shadow: none!important;outline: none!important; min-inline-size: 100%;\">\n                    <legend class=\"ff_screen_reader_title\" style=\"display: block; margin: 0!important;padding: 0!important;height: 0!important;text-indent: -999999px;width: 0!important;overflow:hidden;\">Fluent Forms Text Area Field Max Character Length<\/legend>        <div\n                style=\"display: none!important; position: absolute!important; transform: translateX(1000%)!important;\"\n                class=\"ff-el-group ff-hpsf-container\"\n        >\n            <div class=\"ff-el-input--label asterisk-right\">\n                <label for=\"ff_4_item_sf\" aria-label=\"Newsletter\">\n                    Newsletter                <\/label>\n            <\/div>\n            <div class=\"ff-el-input--content\">\n                <input type=\"text\"\n                       name=\"item_4__fluent_sf\"\n                       class=\"ff-el-form-control\"\n                       id=\"ff_4_item_sf\"\n                \/>\n            <\/div>\n        <\/div>\n        <input type='hidden' name='__fluent_form_embded_post_id' value='956' \/><input type=\"hidden\" id=\"_fluentform_4_fluentformnonce\" name=\"_fluentform_4_fluentformnonce\" value=\"3bc9be6340\" \/><input type=\"hidden\" name=\"_wp_http_referer\" value=\"\/blog\/wp-json\/wp\/v2\/posts\/956\" \/><div class='ff-el-group'><div class=\"ff-el-input--label asterisk-right\"><label for='ff_4_2_description' id='label_ff_4_2_description' aria-label=\"Textarea\">Textarea<\/label><\/div><div class='ff-el-input--content'><textarea aria-required=\"false\" aria-labelledby=\"label_ff_4_2_description\" name=\"description\" id=\"ff_4_2_description\" class=\"ff-el-form-control haslimit\" rows=\"3\" cols=\"2\" data-name=\"description\" ><\/textarea><\/div><\/div><div class='ff-el-group ff-text-left ff_submit_btn_wrapper'><button type=\"submit\" class=\"ff-btn ff-btn-submit ff-btn-md ff_btn_style wpf_has_custom_css\"  aria-label=\"Submit Form\">Submit Form<\/button><\/div><\/fieldset><\/form><div id='fluentform_4_errors' class='ff-errors-in-stack ff_form_instance_4_2 ff-form-loading_errors ff_form_instance_4_2_errors'><\/div><\/div>            <script type=\"text\/javascript\">\n                window.fluent_form_ff_form_instance_4_2 = {\"id\":\"4\",\"ajaxUrl\":\"https:\\\/\\\/aimahdi.com\\\/blog\\\/wp-admin\\\/admin-ajax.php\",\"settings\":{\"layout\":{\"labelPlacement\":\"top\",\"asteriskPlacement\":\"asterisk-right\",\"helpMessagePlacement\":\"with_label\",\"errorMessagePlacement\":\"inline\",\"cssClassName\":\"\"},\"restrictions\":{\"denyEmptySubmission\":{\"enabled\":false}}},\"form_instance\":\"ff_form_instance_4_2\",\"form_id_selector\":\"fluentform_4\",\"rules\":{\"description\":{\"required\":{\"value\":false,\"message\":\"This field is required\",\"global_message\":\"This field is required\",\"global\":true}}},\"debounce_time\":300};\n                            <\/script>\n            \n\n\n\n<h4 class=\"wp-block-heading\">Conclusion<\/h4>\n\n\n\n<p>By following these steps, you can easily implement a max text length limit for&nbsp;<strong>text area fields<\/strong>&nbsp;in Fluent Forms. This approach is highly customizable and can be adapted to suit your specific requirements. Whether you\u2019re building a feedback form, a comment section, or any other type of form, this technique ensures that users stay within the defined character limits.<\/p>\n\n\n\n<p>Feel free to experiment with the code and customize it further to match your form\u2019s design and functionality. Happy form building!<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Pro Tip<\/strong>: If you need to apply this functionality to multiple text area fields, consider using a loop to target all fields with the&nbsp;<code>haslimit<\/code>&nbsp;class.
