Running Grid API Commands

To run a grid API command use the grid's run_api() method. The method accepts two arguments. The first is a string representing the command and the second is the page the grid is on.

The example below uses the grid API to select and deselect rows.

import justpy as jp

grid_options = """
    rowSelection: 'multiple',
    defaultColDef: {
        filter: true,
        sortable: true,
        resizable: true,
        cellStyle: {textAlign: 'center'},
        headerClass: 'font-bold'
      columnDefs: [
      {headerName: "Make", field: "make"},
      {headerName: "Model", field: "model"},
      {headerName: "Price", field: "price"}
      rowData: [
      {make: "Toyota", model: "Celica", price: 35000},
      {make: "Ford", model: "Mondeo", price: 32000},
      {make: "Porsche", model: "Boxter", price: 72000}
