 **判断是不是"新行"**：写入 range 超出 `+csv-get` 返回的 `current_region` 右 / 下边界（如 `current_region=A1:H10`、写 `A11:H11`）即新行，必须按上述做法补边框。
 
+## Dropdown 选项 + 配色（`+dropdown-set` / `+dropdown-update`）
+
+### 选项怎么来：`--options` 与 `--source-range` 二选一
+
+| flag | 选项来源 | 适用场景 |
+|---|---|---|
+| `--options '["a","b","c"]'` | 写在命令里的固定列表 | 选项集是常量、不需要事后维护 |
+| `--source-range 'Sheet1!T1:T3'` | 已有单元格里的值 | 选项要跟数据动态同步；想维护一张「枚举值」列后多处引用 |
+
+两个 flag **必须传一个、且只能传一个**——同时传或都不传，CLI 会立刻报错。`--source-range` 用 A1 + sheet 前缀写法（如 `Sheet1!T1:T3`），可以指同 sheet 也可以指其它 sheet（如 `Refs!A1:A10`）。
+
+### 配色：`--colors` 与 `--highlight`（与选项模式无关）
+
+- `--highlight`：开下拉选项的胶囊背景色总开关；不传默认 `false`、无配色。
+- `--colors '["#hex","#hex",...]'`：每个选项对应一种胶囊背景色；只在 `--highlight` 也传时生效。
+
+长度规则：
+- `--colors` 长度**可以短于**选项数（list 模式短于 `--options` 长度，listFromRange 模式短于 `--source-range` 的单元格数），未指定的选项按内置 10 色色板循环补色；
+- `--colors` 长度**不能长于**选项数——CLI 端 Validate 阶段就会拦截，错误信息形如 `--colors length (4) must not exceed dropdown source size (3)`。
+
+排列组合：
+- 想要纯文本下拉、无配色 → 都不传 `--highlight` / `--colors`；
+- 想要每个选项指定确切颜色 → 同时传 `--highlight` 和 `--colors`；
+- 想要所有选项都有颜色但不指定具体色 → 只传 `--highlight`，颜色按内置色板循环。
+
+### 最小用例
+
+**`--options` 模式**（4 个选项配 3 个颜色——前 3 个指定色，第 4 个按内置色板补）：
+
+```
+lark-cli sheets +dropdown-set \
+  --url https://... --sheet-id <id> \
+  --range A2:A100 \
+  --options '["待开始","进行中","已完成","已取消"]' \
+  --colors '["#bff7d9","#FFE699","#bacefd"]' \
+  --highlight
+```
+
+**`--source-range` 模式**（先在 Sheet1!T1:T3 维护「男/女/保密」三行，再让 B2:B21 引用它）：
+
+```
+lark-cli sheets +dropdown-set \
+  --url https://... --sheet-id <id> \
+  --range B2:B21 \
+  --source-range 'Sheet1!T1:T3' \
+  --colors '["#cce8ff","#ffd6e7","#e6e6e6"]' \
+  --highlight
+```
+
+> ⚠️ **`--source-range` 必须带 sheet 前缀**（即使跟 `--range` 同 sheet）。注意一个坑：回读这种 listFromRange 下拉单元格时，`data_validation.range` 看起来不带 sheet 前缀（形如 `$T$1:$T$3`），如果要把读出来的 range 反过来写回 `--source-range`，**必须自己重新补上 sheet 前缀**，否则会被拒。
+
+`+dropdown-update`（多 range 批量更新）的所有 flag 语义与 `+dropdown-set` 完全一致；只是目标 `--ranges` 由单值变成 JSON 数组（每项带 sheet 前缀），同一份选项 + 配色应用到所有 range。
