    @Override
    public String renderTemplate(FormData formData, Map dataModel) {
        String templateName = "textField.ftl";

        // set value
        String value = FormUtil.getElementPropertyValue(this, formData);
        dataModel.put("value", value);

        String html = FormUtil.generateElementHtml(this, formData, templateName, dataModel);
        return html;
    }

<div class="form-cell" ${elementMetaData!}>
    <label class="label">
        ${element.properties.label} <span class="form-cell-validator">${decoration}</span>
        <#if error??>
            <span class="form-error-message">${error}</span>
        </#if>
    </label>
    <#if (element.properties.readonly! == 'true' && element.properties.readonlyLabel! == 'true') >
        <div class="form-cell-value"><span>${value!?html}</span></div>
        <input id="${elementParamName!}" name="${elementParamName!}" type="hidden" value="${value!?html}" />
    <#else>
        <input id="${elementParamName!}" name="${elementParamName!}" type="text" size="${element.properties.size!}" value="${value!?html}" maxlength="${element.properties.maxlength!}" <#if error??>class="form-error-cell"</#if> <#if element.properties.readonly! == 'true'>readonly</#if> />
    </#if>
</div>
