Hello guys!!

I have this code:

<tree string="PaySlips" create="false" edit="false" delete="false" colors="green:is_data_available=='ok';red:is_no_data=='ok';">

and i have an other condition which is when the field state_contract false or true.

So that i want to add an option which rule out the tree when the state_contract is false.

Who can help please.

Regards.
