# Editing
> Nextedy GANTT provides multiple ways to edit work item data directly within the Gantt chart, from inline field editing to the full lightbox editor.
export const LastReviewed = ({date}) => {
if (!date) return null;
const formatted = new Date(`${date}T00:00:00Z`).toLocaleDateString("en-US", {
year: "numeric",
month: "long",
day: "numeric",
timeZone: "UTC"
});
return
Last reviewed on {formatted}
;
};
Open and configure the lightbox for editing work item fields directly from the Gantt chart.
Add custom fields to the create dialog that appears when adding new work items.
Configure progress tracking, display the progress bar, and use drag handles for quick updates.
Edit task fields directly in the grid columns without opening the lightbox.
Reverse or re-apply recent changes during an editing session.
Control whether child tasks move together with their parent during drag operations.
Manage unsaved edits and prevent data loss from Polarion session timeouts.
The Gantt chart supports three editing modes: **standard** (click Edit to enter edit mode), **always edit** (tasks are immediately draggable), and **read-only** (no editing allowed). Configure the mode through widget parameters or administration properties.
