Filtering conditions dropdown now have a limited height (4 items and a scrollbar) so please take a look at the case where it goes under the summaries.

We can increase the z-index of .igx-grid__outlet from 2 to 1003 in order to make it bigger than the z-index of the footer, I test that and it fixes the issue @simeonoff are you ok with that?

[desig9stein]

Here is a table with all z-index added form SCSS

@desig9stein thanks for the z-index mapping, however, without markup context it's still difficult to grasp the z-index structure. Also, I don't think this table takes into account all dynamically assigned z-index values.
