Dealing with invisible components

In some cases, it can occur that a page in a low-code app or a dashboard contains components that are not shown but that do influence the page or dashboard, causing unexpected behavior.

To check if this is the case, do the following in the dashboard or on every page and panel of the low-code app:

  1. Press Ctrl + A and then press Delete.

  2. Count the components mentioned in the dialog to see if they match the shown components, and then click Cancel.

    If the count matches up, the page, panel, or dashboard does not contain invisible components.

  3. If the count does not match up, clear the selection of the components you can see by clicking them while keeping Ctrl pressed, and then press Delete again to remove the invisible component.
