No, there is not...
What would you expect as a filter ?

I want to tag the test cases to test session & on this screen filter option is not working.

Steps:
open test session page -- > select the test session -- > click on add [Test case run] -- > click on search button -- > click on filter button.

No options are visible.

Looking to filter the test case based on the parent test case.

Steps:
open test session page -- > select the test session -- > click on add [Test case run] -- > click on search button -- > click on filter button.
No options are visible.

Are you sure you have some test cases ?
Do you have a project selected on project selector (filter is applied toi search box)

OK, I got it.
There seems to be an issue.
I did not find at first as I thought it was a Tast Case issue.
In fact issue also occurs on other combo lists (for instance if you want to link a item)

Ticket #2309.
As a workaroud, you can go to ticket view, define your filter and stroe it.
You'll then be able to activate it directly with just a mouse over the filter button

Hi,
