哪个是用bem命名下拉菜单的最佳方法?使用儿童nav-main__sub或修改器nav-main - sub ??
<ul class="nav nav-main">
<li class="nav__item">
<a href="#" class="nav__link is-active">home</a>
</li>
<li class="nav__item nav__item--sub-nav">
<a href="#" class="nav__link">About</a>
<ul class="nav nav-main--sub">
<li class="nav-main--sub__item">
<a href="#" class="nav-main--sub__link">Company</a>
</li>
</ul>
<li class="nav__item">
<a href="#" class="nav__link">Contact</a>
</li>

恕我直言<ul class="nav nav--main">
<li class="nav__item nav__item--sub-nav">
<a href="#" class="nav__link">About</a>
<ul class="nav nav-main__sub">
<li class="nav-main__sub-item">
<a href="#" class="nav-main__sub-link">Company</a>
</li>
</ul>
</li>
</ul>
,因为它不是修饰语。
<ul class="nav nav--main">
<li class="nav__item nav__item--sub-nav">
<a href="#" class="nav__link">About</a>
<ul class="sub">
<li class="sub__item">
<a href="#" class="sub__link">Company</a>
</li>
</ul>
</li>
</ul>
或更容易:
COPY res_partner(name, website,email,phone)
FROM '/home/ubuntu/sample/data.csv'
WITH DELIMITER ','
CSV HEADER;
templ=# SELECT count(*) FROM res_partner;
count
