Hi linda,

Yes, sure just place it in smart-window component and it will work and the keyboard navigation and focus are enabled by default.

Hi,

Define Translations via messages

Smart.Gantt lets you override all UI text per locale:

const gantt = document.querySelector("smart-gantt");

gantt.messages = {
  en: {
    task: "Task",
    startDate: "Start Date",
    endDate: "End Date",
    duration: "Duration"
  },
  es: {
    task: "Tarea",
    startDate: "Fecha de inicio",
    endDate: "Fecha de fin",
    duration: "Duración"
  },
  fr: {
    task: "Tâche",
    startDate: "Date de début",
    endDate: "Date de fin",
    duration: "Durée"
  }
};

Set the Active Locale

gantt.locale = "es"; // Spanish

Use Messages in Columns (Labels)

Instead of hardcoding labels, pull from messages:

gantt.treeColumns = [
  { label: gantt.localize("task"), value: "label", size: "50%" },
  { label: gantt.localize("startDate"), value: "dateStart" },
  { label: gantt.localize("endDate"), value: "dateEnd" }
];

👉 localize(key) automatically uses the current locale.

4. Localize Tooltips

Smart.Gantt allows tooltip customization via templates or callbacks.

Example:

gantt.tooltipTemplate = function(task) {
  return 

${gantt.localize(“task”)}: ${task.label}
${gantt.localize(“startDate”)}: ${task.dateStart}
${gantt.localize(“endDate”)}: ${task.dateEnd}
`;
};

Localize Dates Properly (Important)

Smart.Gantt does not fully localize date formatting automatically in templates, so use the browser API:

function formatDate(date, locale) {
return new Intl.DateTimeFormat(locale).format(new Date(date));
}

gantt.tooltipTemplate = function(task) {
return `
${gantt.localize(“task”)}: ${task.label}
${gantt.localize(“startDate”)}: ${formatDate(task.dateStart, gantt.locale)}
${gantt.localize(“endDate”)}: ${formatDate(task.dateEnd, gantt.locale)}
`;
};`

Hi,

All you need to do is to dynamically set the dataSource property to a new value.

Example:

const scheduler = document.querySelector('smart-scheduler');

// SET / REPLACE DATA (preferred for async updates)
scheduler.dataSource = [
  { id: 1, label: 'Event A', dateStart: new Date(), dateEnd: new Date() }
];

// UPDATE EXISTING EVENT (requires refresh)
const e = scheduler.dataSource.find(x => x.id === 1);
e.dateEnd = new Date(Date.now() + 3600_000);
scheduler.refresh();

// ADD EVENT
scheduler.dataSource = [
  ...scheduler.dataSource,
  { id: 2, label: 'Event B', dateStart: new Date(), dateEnd: new Date() }
];

// REMOVE EVENT
scheduler.dataSource = scheduler.dataSource.filter(x => x.id !== 1);

Hi,

I tried to reproduce this in our https://www.htmlelements.com/demos/table/column-menu/, but could not. Could you share a sample we can test with or exact steps?

Hi,

Yes, you can append it to the DOM dynamically or data bind it when you want by setting its dataSource property to a data.

Hi,

You can try this way:

const input = document.getElementById('myInput');

input.addEventListener('change', (event) => {
  console.log('Value changed:', event.target.value);
});
