在主题的functions.php文件中查找

function themeConfig($form) {

在下面插入

    $sticky = new Typecho_Widget_Helper_Form_Element_Text('sticky', NULL, NULL, _t('置顶文章cid'), _t('多篇文章以`|`符号隔开'), _t('会在首页展示置顶文章。'));
    $form->addInput($sticky);

在文章列表中合适的地方插入,一般是<?php $this->title() ?>的前后位置

<?php if (isset($this->isSticky) && $this->isSticky): ?>
<?php echo $this->stickyHtml; ?>
<?php endif; ?>
