      <div class="field ">

        <label for="custom_field" class="label"><span><?= __('affiliateEmail') ?></span></label>

        <div class="control">

            <input type="text" name="affiliate_email" id="affiliate_email" value="<?= $block->escapeHtml($block->getFormData()->getCustomField()) ?>" title="<?= __('affiliateEmail') ?>" class="input-text" data-validate="{required:false,'validate-email':true}">

        </div>

    </div>
