"summary": "CSS 端的 cascader:.kole-cascader-trigger 是触发器,is-open 展开 .kole-cascader-panel 多列面板。",
"usage": [
"外层 .kole-cascader 是 position:relative 加 min-width:200px,是下拉面板的定位参照(frameworks/Cascader.css:3)。",
"触发器 .kole-cascader-trigger 展开时加 .is-open:品牌边框加 2px 光晕,同时把内部 .caret 旋转 180 度(frameworks/Cascader.css:9、12)。",
"未选中时显示占位文字,用 .placeholder 内联类取 --kole-color-text-placeholder(frameworks/Cascader.css:10)。",
"已选值用标签排:.kole-cascader-tags 横向换行,单枚 .kole-cascader-tag 是品牌浅底小胶囊(frameworks/Cascader.css:13-14)。",
"面板 .kole-cascader-panel 绝对定位在触发器下方 4px、z-index 100;每列 .kole-cascader-col 最小 140px、最高 240px 可滚动,末列去掉右分隔线(frameworks/Cascader.css:16-18)。",
"列内选项 .kole-cascader-opt:hover 用页面底色,.is-active 换品牌浅底加品牌字色,多选时 .is-checked .box 填品牌色(frameworks/Cascader.css:19-24)。",
"搜索层 .kole-cascader-search 是独立浮层(z-index 101、宽 260px),输入框聚焦换品牌边框,结果区 .kole-cascader-results 最高 200px 可滚(frameworks/Cascader.css:26-32)。"

"bestPractices": [
"面板层级要留意:面板 z-index 100、搜索层 101,两者都绝对定位在触发器下方;同屏有更高层级弹层时需在业务侧统一层级(frameworks/Cascader.css:16、26)。",
"多选勾选框 .box 只在 .is-checked 时被填色,选中逻辑仍要由脚本切类,样式不会自勾(frameworks/Cascader.css:23-24)。",
"列滚动用 max-height:240px 配 overflow:auto,选项很多时靠这层滚动而不是整体拉高面板(frameworks/Cascader.css:17)。"
],
"a11y": [
"触发器展开态只用边框与光晕表达,建议同时维护 aria-expanded,样式层不提供该属性(frameworks/Cascader.css:9)。",
"搜索输入框的 focus 只有边框+光晕、没有 outline,键盘用户依赖这层视觉,请勿在业务侧取消(frameworks/Cascader.css:28)。",
"勾选框是 14px 的 .box 内联块,尺寸偏小且非原生控件,建议在外层元素上补 aria-checked 等语义(frameworks/Cascader.css:23-24)。"
