Dale, I've seen this question before and I'll say what I said then. There is no way built into displaytag to do this. I'm sure you could come up with a way to do it. Just because you can come up with a way to do it, though, doesn't make it a good idea. As an interface element, having selections that are no longer viewable or editable is a really bad idea. I understand the *requirement*, but the solution isn't advisable.
Instead, you should look at the idea of having an accumulation list accompany your display table. By that, I mean something where the user selects one or more items from the currently displayed page (with the checkbox controls identified by, e.g., database ID, list index, or whatever) then clicks an Add button. This adds the selected items to a list to the right of the display table. Then, as the user pages through the display table, the selected items are always viewable in the accumulation list. Items can be removed from the accumulation list with a remove button. So the interface looks something like this (fixed font req'd): ( ) Item 1 (Empty) ( ) Item 2 Add-> ( ) Item 3 <-Del ( ) Item 4 Now select Item 2. ( ) Item 1 (Empty) (*) Item 2 Add-> ( ) Item 3 <-Del ( ) Item 4 Click Add: ( ) Item 1 ( ) Item 2 ( ) Item 2 Add-> ( ) Item 3 <-Del ( ) Item 4 Go to next page: ( ) Item 5 ( ) Item 2 ( ) Item 6 Add-> ( ) Item 7 <-Del ( ) Item 8 There ya go.
