show
show
is used as a parameter to section.
show
is a boolean value, true or false. If false, the section will not be displayed.
If there is a sectionelse present, that will be alternately displayed.
show 是 section 的参数. show 取值为布尔值 true 或 false. 如果设置为 false，该循环将不显示.
如果指定了 sectionelse 子句，该字句是否显示也取决于该值.
