Currently I am using odoov8, my problem is that I have created many filters from xml code as per my requirement and all are working fine ,but I can select only one filter at a time .
so for example I want to apply any 3 Filters in tree view , then I need to select first one , then system loads the data , then I select 2nd and then 3rd filter , so system is loading after applying each filter .
I want to achieve that if I can select all my filters at once and then I can apply search , so system loads after I apply for search , no matter how much time it taking but I should not require to search single filter .
so is there any custom module or way from which I can achieve this .
Thanks in advance .
