how to toggle in vertical direction

i want to use the vertical toggling in vertical direction like in rediff so that when user clicks on the row of table it toggles downwards to show other information in may be a textarea or whatever

What do you mean by this - something like what is requested

Some things can be done with a
, while others are not supported by the current table implementation. In most cases the additional information does not necessarily need to be inside the table but can e.g. be separately underneath it.

If the information does not need to be in a single Table, also take a look at the
Drawer add-on
