Question details

Users want to open the New Item or Edit form in Microsoft Lists in a full-screen window rather than the default right-side panel.

How to Open Microsoft Lists New Item in Full Screen

Product: Microsoft Lists
Device & OS: not provided
Scenario: Creating or editing a record in a modern Microsoft List.
Observed behavior: Forms open in a right-side panel by default, and changing the traditional 'Dialogs' setting no longer restores the full-screen view in the modern experience.

Before you start

Ensure you have the necessary list permissions to edit column settings and apply custom JSON formatting to your Microsoft List views.

Use JSON Column Formatting to Link to the Full-Screen Edit Page

Since there is no built-in toggle to force a full-screen layout in the modern experience, you can use JSON column formatting on the Title column to redirect item clicks directly to the classic EditForm.aspx page.

The traditional 'Launch forms in a dialog' option does not affect the modern experience's side-panel behavior. By applying a custom JSON script, you can override the default click action of the Title column so that it opens the full-screen form in a new tab.

Access column settings

Navigate to your Microsoft List, click on the header of the 'Title' column, and select 'Column settings' followed by 'Format this column'.

Enable advanced mode

At the bottom of the formatting pane that appears on the right, click on 'Advanced mode' to allow custom JSON input.

Apply the JSON code

Paste the following JSON to redefine the link behavior: {"$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json", "elmType": "a", "txtContent": "@currentField", "attributes": {"href": "=@currentWeb + '/Lists/YourListPath/EditForm.aspx?ID=' + [$ID] + '&Source=' + @currentWeb + '/Lists/YourListPath/'", "target": "_blank"}}.

Update the list path and save

Carefully replace 'YourListPath' in the JSON script with the actual URL path of your specific list. Click 'Save' to apply the formatting. Clicking the title will now open the full-screen edit page.

Use JSON Column Formatting to Link to the Full-Screen Edit Page

URL Customization Required: The JSON script relies on the exact URL of your list. If your list is named 'ProjectTracker', ensure 'YourListPath' is updated to 'ProjectTracker' in both instances within the code.

Frequently Asked Questions

Why did Microsoft Lists change the form view to a side panel?

Microsoft updated the modern list experience to allow users to quickly view and edit item details without losing the context of the entire list view. As a result, new item and edit forms open in a side panel by default.

Does the 'Launch forms in a dialog' setting still work?

In the classic SharePoint experience, this setting controlled form pop-ups. However, in the modern Microsoft Lists experience, changing the Dialogs setting in Advanced Settings no longer reverts the side panel back to a full-screen view.

Can I apply this JSON formatting to columns other than the Title?

Yes, you can apply this JSON formatting to any text column in your list. However, it is highly recommended to apply it to the Title column, as users intuitively click the title to view or edit an item's details.
