  • Device preview, previously desktop-only, is now available in web edit as of Tableau 2021.1, provided you have edit permissions on the workbook
  • Tableau can auto-generate a phone layout, indicated by a padlock icon; locking keeps it auto-generated while unlocking lets you move and adapt elements yourself
  • Right-clicking the device preview tab lets you add phone, tablet and desktop layouts as a hierarchy beneath the default view, and the three-dot menu deletes them
  • You can pick specific device models via the device preview tab, such as a small iPad, large iPad or Samsung tablet, then click add layout to apply it

Tableau 2021.1 brings device preview (phone, tablet, desktop layouts) into web edit, so you no longer need Desktop just to tweak how a dashboard looks on different devices.

Tim uses a published workbook in Tableau Online to demonstrate editing device layouts entirely from the browser rather than in Desktop.

The Breakdown
  1. Open a workbook you can edit 0:41

    You need edit permissions on the workbook to see the edit button; without them the device preview editing options won't appear.

  2. Enter web edit and find the auto-generated phone layout 1:02

    Clicking edit opens a dashboard-style editor in the browser, and Tableau may already have auto-generated a phone layout for you, shown on the left.

  3. Understand the lock icon on auto-generated layouts 1:21

    A locked padlock means the layout is auto-generated by Tableau; unlocking it lets you manually move and adapt elements to suit the device, at the cost of losing auto-generation.

  4. Add or remove device layouts via right-click 1:57

    Right-clicking the device preview tab lets you add phone, tablet or desktop layouts, which stack as a hierarchy beneath the default view (the view everyone sees by default); the three-dot menu next to each layout deletes it.

  5. Choose a specific device model instead of a generic layout 2:49

    As an alternative to the generic layout types, open the device preview tab, pick a device type not already added, then select a specific model (e.g. small iPad, large iPad, Samsung tablet) before clicking add layout to apply it.

  6. Everything else works like desktop dashboarding 3:41

    Once a layout is added, you get the same dashboard layout capabilities you'd have in Desktop, so existing dashboarding skills carry over directly.

Worth Knowing
  • You must have edit permissions on the workbook to access device preview editing in the browser at all.
  • Locking a layout keeps it auto-generated; unlocking gives manual control but removes the automatic adaptation.
  • Tim notes browser editing still lags behind Desktop overall, though he expects it to catch up.
Use It When

Reach for this when you spend most of your time developing dashboards in the browser and just need to check or tweak a mobile or tablet layout without switching to Desktop.

How this Rollup was made provenance & method

A Rollup is drafted by AI from the video's transcript, then reviewed and edited by Tim. Everything used to produce this one is listed below — the model, the exact prompt, and the source video — so the process is transparent and reproducible.
