For most PMWeb records, the Main tab is comprised of fields at the top of the page - called the header - and a table of record details at the bottom.
When viewed on a typical desktop screen, the header can have up to three columns of fields. On narrower screens, PMWeb automatically adjusts itself to show two columns or, if necessary, only one column. Columns "stack" themselves in this order as you move to smaller screens:
Column 3 moves under column 2.
Column 2 and 3 move under column 1.
You can scroll vertically to view all of the data fields in logical order.
On devices with very narrow screens, several things happen:
The Control Panel disappears.
The PMWeb logo, the breadcrumbs, and the Exit PMWeb button all move to a bottom bar. (See Control Panel)
The Main tab divides into the Header and Details tabs. By moving the details table to its own tab, PMWeb can load significantly faster on devices which have less powerful processors and fewer system resources than a desktop computer.
