Use of levels
As mentioned, every user is assigned a level. There are 16 possible levels, identified with a number from 0 to 15.Level 0 is the least important, while level 15 is usually assigned to the machine administrator.Each variable inside grids allows to configure its property “userlevels”: it indicates which levels have write access to the variable.
Allowed levels must be specified comma separated. With special word “ALL” the variable will be writeable by all levels.The use of levels lets you further customize pages created with View according to the user associated. You can also completely hide or show a page to users assigned to a certain level.The ACL property on all pages lets you define the action to be taken for each level. The page may be restricted (deny) or display may be directed to another page. Normally, the page is displayable at all levels (allow).
While you compose the page, you can also insert panels that appear or disappear according to the active level.For example, on the menu at the left, under Organize, if you pick a SmartPanel and place it on a page, you will find the property levelsHidden. This item lets you select the levels for which the panel must not be displayed, comma separated. Levels 0, 1, and 2 are set in the example.
