To make certain cells have drop-down menus in Material-Table, you will need to utilize the cellEditable property and define a custom render component for the cells that need the drop-down menus. Here's a general example to demonstrate how this can be achieved:
First, you need to define the data source that will populate the drop-down menus in each cell. For this example, let's say we have an array of options:
javascript
Copy code
const options = ['Option 1', 'Option 2', 'Option 3'];
Next, we will define the custom render component for the cells that need the drop-down menus. In this component, we will use the select element to display the options as a drop-down menu:
javascript
Copy code
const DropdownRender = ({ rowData, columnDef }) => {
return (
<select
value={rowData[columnDef.field]}
onChange={e => {
rowData[columnDef.field] = e.target.value;
}}
>
{options.map(option => (
<option key={option} value={option}>
{option}
</option>
))}
</select>
);
};
In the Material-Table component, we will define the columns property, where we will specify which columns need to have the drop-down menus. For each column, we will use the cellEditable property to set the value to true. We will also set the render property to the custom render component we defined in step 2.
yaml
Copy code
<MaterialTable
columns={[
{ title: 'Column 1', field: 'column1', cellEditable: true, render: DropdownRender },
{ title: 'Column 2', field: 'column2', cellEditable: true, render: DropdownRender },
{ title: 'Column 3', field: 'column3', cellEditable: false },
]}
data={data}
actions={[
{
icon: 'edit',
tooltip: 'Edit',
onClick: (event, rowData) => {
// handle the Edit Action here
},
},
]}
/>
Finally, when the Edit Action button is clicked, the cells in the specified columns will have drop-down menus that allow the user to select a value from the options array.
This is just a basic example to get you started. You can further customize the custom render component to meet your specific needs, such as adding styling or conditionally rendering the drop-down menus based on certain conditions.
To make certain cells in Material-Table have drop-down menus on clicking the Edit Action button, you can use the editComponent property in the column definition to render a custom component with a select input. Here's a basic example:
javascript
Copy code
import React from 'react';
import { Select, FormControl } from '@material-ui/core';
import MaterialTable from 'material-table';
const DropdownCell = ({ value, onChange }) => (
<FormControl>
<Select value={value} onChange={onChange}>
<option value="option1">Option 1</option>
<option value="option2">Option 2</option>
<option value="option3">Option 3</option>
</Select>
</FormControl>
);
const tableData = [
{ name: 'John Doe', city: 'New York', state: 'NY' },
{ name: 'Jane Doe', city: 'Los Angeles', state: 'LA' },
{ name: 'Jim Smith', city: 'Chicago', state: 'IL' },
];
const MyTable = () => (
<MaterialTable
columns={[
{ title: 'Name', field: 'name' },
{
title: 'City',
field: 'city',
editComponent: ({ value, onChange }) => (
<DropdownCell value={value} onChange={onChange} />
),
},
{
title: 'State',
field: 'state',
editComponent: ({ value, onChange }) => (
<DropdownCell value={value} onChange={onChange} />
),
},
]}
data={tableData}
editable={{
onRowUpdate: (newData, oldData) =>
new Promise((resolve) => {
setTimeout(() => {
resolve();
console.log(newData);
}, 600);
}),
}}
/>
);
export default MyTable;
In the example, we define a custom component DropdownCell that takes in the current value and onChange function, and returns a FormControl with a Select input. Then in the column definition, we set the editComponent property to a function that returns the DropdownCell component. When the Edit Action button is clicked, the DropdownCell component will be rendered in place of the cell.
You can customize the options in the drop-down menu by changing the options in the Select input. You can also update the onChange function to handle the changes in the selected value and save the changes to the backend or update the state.
