当我转到页面时，出于某种原因，最后一个选项卡始终处于活动状态，但是有必要使第一个选项卡处于活动状态。我不明白为什么会这样。看来如果i=0处于活动状态，则第一个处于活动状态；如果没有激活，则表示没有任何攻击，由于某种原因，它总是跳至最后一个。请帮助
foreach( $taxonomies as $taxonomy ) :
// Gets every "category" (term) in this taxonomy to get the respective posts
$terms = get_terms( $taxonomy ); ?>
<div class="category-title">

<ul class="nav nav-tabs" id="myTab" role="tablist">
<?php
$i=0;
foreach( $terms as $term ) {
if($i==0){
