jqgrid ExpandColClick 树形

Yes, the "jqgrid ExpandColClick" feature can be used to create a tree-like structure in the jqGrid plugin for jQuery. When the feature is enabled, clicking on the "+" icon in the first column of a row can expand the row to show additional information or sub-rows, creating a hierarchical structure.

To create a tree-like structure using "jqgrid ExpandColClick", you will need to set up your data in a hierarchical format, with parent-child relationships between rows. You can then use the "ExpandColClick" feature to allow users to expand and collapse the rows as needed.

Here is an example of how you might set up the data for a tree-like structure in jqGrid:

var myData = [
  { id: 1, name: "Parent 1", parent: null },
  { id: 2, name: "Child 1-1", parent: 1 },
  { id: 3, name: "Child 1-2", parent: 1 },
  { id: 4, name: "Parent 2", parent: null },
  { id: 5, name: "Child 2-1", parent: 4 },
  { id: 6, name: "Child 2-2", parent: 4 }
];

In this example, each row has an "id" and "name" field, as well as a "parent" field that indicates the ID of its parent row. Rows with a "null" parent field are considered to be top-level rows.

To enable the "jqgrid ExpandColClick" feature in your grid, you can set the "ExpandColClick" property to "true" in the jqGrid configuration options:

$("#myGrid").jqGrid({
  data: myData,
  colModel: [
    { name: "name", label: "Name", width: 200 },
    // other columns...
  ],
  ExpandColClick: true
});

With this configuration, the "+" icon will be displayed in the first column of each row that has child rows, and clicking on the icon will expand or collapse the row as needed.
