Including all as a selection option in the listbox

[#1]

Hi Guys,

I have a very strange requirement from the client. They want 'All' as an option in the list box which should mean everything selected from that filter. I know if nothing is selected from a listbox, it is same as everything selected from that listbox but i want to know whether we can do that in qlikview or not. If yes, how can we do that?

basicly i think explaining to the customer how qlikview works is better

another solution is to add the select all button to the caption

have a look at the attach picutre

Thanks for the reply liron.

But explaining customer would be the last option. Before that, i want to explore all the possibilities. 'Select All' button is fine but can't we give a dummy value 'ALL' in the listbox so that when we select 'ALL', nothing should happen but if we select some other value then it should filter the data in the document.
