hi there
we are using hikashop 2.3.3 and we run an online bookshop in Iran .
for special reasons we cant update joomla and hikashop and we have to solve problems manually.

when we want to provide an advance search with filters for users , the only filter that work in search is "place holder". this means the only fields we could provide are "price" and "weigh filters" for advance search.
for example when we create text filter or "radio-box" or "drop down" these filters wont work and "drop down" do not load data from special fields that we define, and nothing found in search result . how can we solve this problem manually without update?

we have an another problem: when we create characteristic for product for example colors. when the customer is choosing color in ordering process it does not include Shopping Cart .

my last quastion is how can i add "status of the order" in invoice .

best regards.
