selectionGroup :: CGIMonad cgi => WithHTML y cgi (SelectionGroup AR INVALID)

Create a selection group for a table. Selects one row.

selectionButton :: CGIMonad cgi => SelectionGroup AR INVALID -> AT -> Int -> HTMLField cgi x y ()

Create a selection button for an abstract table

selectionDisplay :: CGIMonad cgi => SelectionGroup AR INVALID -> AT -> Int -> (WithHTML x cgi () -> [WithHTML x cgi ()] -> WithHTML x cgi a) -> WithHTML x cgi a

Create a labelled selection display for an abstract table. The display function takes the button element and a list of text nodes corresponding to the selected row and is expected to perform the layout.

choiceGroup :: CGIMonad cgi => WithHTML x cgi (SelectionGroup [AR] INVALID)

Create a choice group for a table (0-*).

choiceButton :: CGIMonad cgi => SelectionGroup [AR] INVALID -> AT -> Int -> HTMLField cgi x y ()

Create one choice button for an abstract table

choiceDisplay :: CGIMonad cgi => SelectionGroup [AR] INVALID -> AT -> Int -> (WithHTML x cgi () -> [WithHTML x cgi ()] -> WithHTML x cgi a) -> WithHTML x cgi a

Create a labelled choice display for an abstract table. The display function takes the button element and a list of text nodes corresponding to the selected row and is expected to perform the layout.
