Adding Optional Criteria In A Select Proc

I would like to write 1 proc that can take additional criteria if its sent in. An example is:

select HA.PriceId, HA.VendorPackageId from Criteria HA Inner Join
(
select VendorPackageId from ValidVendorPackages
where Vendor = @VENDOR
and Sitecode = @SITECODE
and PackageType = @PACKAGETYPE
)HB on HA.VendorPackageId = HB.VendorPackageId
and CriteriaId in
(
select CriteriaID from ValidItemCriteria
where Destination = @DESTINATION
and LengthOfStay = @LENGTHOFSTAY
and Ages = @AGE
and ComponentType = @COMPONENTTYPE_1
and ValidItemType = @VALIDITEMTYPE_1
and ItemValue = @ITEMVALUE_1
)


Multiple @COMPONENTTYPE, @VALIDITEMTYPE,@ITEMVALUE can be sent in.
Instead of making multiple procs or copying the proc multiple times with an if statement at the top checking the number of parameters that aren't =''. Is there a way to exectue:

and CriteriaId in
(
select CriteriaID from ValidItemCriteria
where Destination = @DESTINATION
and LengthOfStay = @LENGTHOFSTAY
and Ages = @AGE
and ComponentType = @COMPONENTTYPE_1
and ValidItemType = @VALIDITEMTYPE_1
and ItemValue = @ITEMVALUE_1
)
and CriteriaId in
(
select CriteriaID from ValidItemCriteria
where Destination = @DESTINATION
and LengthOfStay = @LENGTHOFSTAY
and Ages = @AGE
and ComponentType = @COMPONENTTYPE_2
and ValidItemType = @VALIDITEMTYPE_2
and ItemValue = @ITEMVALUE_2
)
and CriteriaId in
(
select CriteriaID from ValidItemCriteria
where Destination = @DESTINATION
and LengthOfStay = @LENGTHOFSTAY
and Ages = @AGE
and ComponentType = @COMPONENTTYPE_3
and ValidItemType = @VALIDITEMTYPE_3
and ItemValue = @ITEMVALUE_3
)

Ignoring the 2nd 2 selects if @COMPONENTTYPE_2, @VALIDITEMTYPE_2,@ITEMVALUE_2 and @COMPONENTTYPE_3, @VALIDITEMTYPE_3,@ITEMVALUE_3 are = ''

Thanks for your help in advance.
