Select

Select settings provide a dropdown menu for users to choose from predefined options. This is ideal for settings that have a fixed set of valid values.

Basic Usage

import { useMMAppSetting } from '@machinemetrics/mm-react-tools';

function MyWidget() {
  useMMAppSetting('metric', {
    label: 'Metric',
    type: 'select',
    options: [
      { label: 'OEE', value: 'oee' },
      { label: 'Utilization', value: 'utilization' },
      { label: 'Availability', value: 'availability' },
    ],
  });
}

Properties

Property	Type	Description
label	string	Display label for the select field
type	"select"	Must be set to "select"
isMulti	boolean	Whether multiple items in the dropdown can be chosen
options	array	Array of option objects with label and value properties
isRequired	boolean	Whether a selection is required
helperText	string	Help text displayed below the select
default	string	Default selected value
validate	function	Validation function for the selected value

Dynamic Options

You can provide options dynamically using a function:

useMMAppSetting('metric', {
  label: 'Metric',
  type: 'select',
  options: () => {
    // Fetch or compute options dynamically
    return [
      { label: 'OEE', value: 'oee' },
      { label: 'Utilization', value: 'utilization' },
    ];
  },
});

Examples

Basic Select with Default Value

useMMAppSetting('timeRange', {
  label: 'Time Range',
  type: 'select',
  default: '24h',
  options: [
    { label: 'Last Hour', value: '1h' },
    { label: 'Last 24 Hours', value: '24h' },
    { label: 'Last Week', value: '7d' },
    { label: 'Last Month', value: '30d' },
  ],
});

Select with Dynamic Options Based on Context

useMMAppSetting('machine', {
  label: 'Machine',
  type: 'select',
  isRequired: true,
  helperText: 'Select a machine to monitor',
  options: () => {
    // Example of dynamic options based on available machines
    return availableMachines.map((machine) => ({
      label: machine.name,
      value: machine.id,
    }));
  },
});

Select with Validation

useMMAppSetting('aggregation', {
  label: 'Aggregation Method',
  type: 'select',
  default: 'average',
  validate: ({ value }) => {
    if (!['average', 'sum', 'min', 'max'].includes(value)) {
      return { message: 'Invalid aggregation method' };
    }
    return null;
  },
  options: [
    { label: 'Average', value: 'average' },
    { label: 'Sum', value: 'sum' },
    { label: 'Minimum', value: 'min' },
    { label: 'Maximum', value: 'max' },
  ],
});

Select with Filterable Options

useMMAppSetting('metric', {
  label: 'Metric',
  type: 'select',
  options: ({ filter }) => {
    const allMetrics = [
      { label: 'OEE', value: 'oee' },
      { label: 'Utilization', value: 'utilization' },
      { label: 'Availability', value: 'availability' },
      { label: 'Performance', value: 'performance' },
      { label: 'Quality', value: 'quality' },
    ];

    // Filter options based on the provided filter string
    if (!filter) return allMetrics;

    return allMetrics.filter((metric) =>
      metric.label.toLowerCase().includes(filter.toLowerCase()),
    );
  },
});

Select with Async Options from API

import { useMMAuth } from '@machinemetrics/mm-react-tools';

function MyWidget() {
  const { request, urls } = useMMAuth();

  useMMAppSetting('machine', {
    label: 'Machine',
    type: 'select',
    options: async ({ filter }) => {
      // Fetch machines from API
      const response = await request(`${urls.apiUrl}/machines`);
      const machines = response.data;

      // Filter machines based on the provided filter string
      if (!filter) return machines;

      return machines.filter((machine) =>
        machine.name.toLowerCase().includes(filter.toLowerCase()),
      );
    },
  });
}
