Kibana 8.3+: Fiilter for filter out buttons should not be displayed if column is not filterable

[dminovski0]

When a user hovers on the left of a Metric column, the filter options appear and they work.

But, when they hover on the left of the Computed column, the filter options appear and don't work on click.

Filter options appear when the user hovers on the right of the computed column too, even if there is no other column after it, and they don't work.

In the version for Kibana 7.17.0, they appeared only next to the Metric column.

Hi,
I just tested with Kibana 7.17.4, with the same configuration than yours, and I can tell you that:

• first, when a user hovers on the left of a Metric column, the filter options appear for the left column, so for "Country" column in your sample. This is not tied to the Metric column.
• then, when a user hovers on the left of the computed column, there is no filter options, given that filter options here would be associated to second column, and as second column is "Count" (not a field based metric), this is not a filterable column.
• finally, when a user hovers on the right of a computed column, there is no filter options as a computed column is not filterable, I mean that is not a "field" of Elasticsearch data, that can be used by Kibana to filter Elasticsearch data. Computed column only exists in the enhanced table visualization, Kibana itself doesn't know the existence of these computed columns.
• That said, there is only one exception: if computed column is simple a filterable column reference (ex: "col0"), then the computed column is filterable, as it references simply a standard filterable column.

Finally, if you really use Kibana 7.17.0, I strongly recommend you to upgrade to more recent patch. For instance, 7.17.25, that is the last 7.17 patch when I write this comment. In the same way, I recommend you to use last Enhanced Table plugin version, that is to say 1.14.0:

Hi, sorry. This appears in the version enhanced-table-1.14.0_8.16.1.zip. As you mentioned, in 7.17.0 it appears only to the left of the "Count" column, for "Country".

[fbaligand]

OK. So you use Kibana 8.16.1 ?

[dminovski0]

Yes, that is where the other filter options appear.

Hi,

I just did tests with Kibana 8.16, and managed to reproduce your issue.
That is a bug.
"Count" column and "Computed Column" should not have filter buttons displayed, because these columns are not "filterable".
I will try to fix it.

That said:

• Filter buttons are displayed on the right of the targeted column
• Don't expect that a "Count" column or a "Computed Column" to be filterable.
• The only exception is "Computed Column" which formula is a simple reference to a filterable column (ex: col0)

After some more tests, I realize that this bug appeared since Kibana 8.3!

[dminovski0]

It seems that it wasn't noticeable, as most users clicked the filters on the leftmost column.

Yes, even me, I didn’t notice it during my tests 😉
This is not a blocking issue, but it’s disturbing.
