Issue with multiple drop-down filters in Constellation app – first drop-down not collapsing

User Experience

Hi Team,

In my Constellation application, I have multiple drop-down filters. I am observing inconsistent behavior when interacting with them:

  • When I select a value from the first drop-down and then click on the second drop-down, sometimes the first drop-down remains open instead of collapsing.

  • Importantly, I do not want the first drop-down value to be reset — the selection should stay intact.

  • The issue is random and inconsistent; it doesn’t happen every time.

My expectation:

  • Clicking on a new drop-down should collapse any previously opened drop-downs.

  • The selected value in the first drop-down should remain unchanged.

Questions:

  1. Why might this random behavior occur in the Constellation drop-downs?

  2. How can I configure or fix the filters so that:

    • Only one drop-down is open at a time.

    • Previously selected values are retained, even when another drop-down is clicked

Thanks in advance for your help!

Hello @Eranda_Weerasingha

Are these Promoted filters linked to each other like cascading dropdowns or just isolated picklist fields?

Is the first dropdown field not getting reset onclick of the reset link you have on the table ?

To my best understanding, these promoted filters are like filters in your report definition rule. Each of the filter is unique and either you manually reset by clearing the field or reset all of them at once on click of the reset link on top of the table.

May be you can trace the Reset button/link click and see if you notice anything unusual in tracer or check the logs as well.

If its intermittent, then it’s a bit difficult to know what’s causing the issue. May be clear the cache and do a clean restart, try incognito window, remove one of the two promoted filters and check if only one is behaving fine..Basically keep hunting the pattern of the error.

Hope this helps

Regards

JC

this is a good Constellation based question, i’m going to move this to our User Experience Expert Circle so it can be found with other related content. Please join the expert circle if you haven’t already done so.

If you post a Constellation question in the future, you can use this category to post to help it get more visiblity / categorisation.

Hi Jayachandra,

Thanks for your response.

Regarding your question — these promoted filters are just isolated picklist fields, not cascading dropdowns.

  • The Case Status filter is using the OOTB feature

  • The other dropdown is populated using a Data Page

  • This is part of Pega SIAA OOTB rules

Also, the issue is intermittent — it does not happen every time, which makes it harder to consistently reproduce.

I will try your suggestions like tracing, checking logs, and testing with cache clear/incognito to identify any pattern.

Thanks again for your guidance!

Thanks Marc, appreciate it. I’ll make sure to use the correct category going forward.

to support @JayachandraSiddipeta’s thoughts. The promoted filter shouldn’t be resetting (not without clicking the reset button).

The fact it is, suggests some sort of issue with the data in the promoted filter. Perhaps the original data for “statut de correction” is sourced from a data page that has parameters attached to it (that are losing context)?

I’d suggest raising a ticket with My Pega Support to investigate your configuration (List View / Insight, Data model etc.) but the Promoted Filter expected behaviour is to not reset (unless reset by click of the reset button)

I misunderstood there.

Ok, yes, the other filters should collapse when you select another. I would raise an incident on My Pega Support so it can be investigated.

Additional info

What version are you using? I know in earlier versions like ‘23, BUG-773048, there were some rendering issues on Insights especially when used on certain templates or with an web embed. (This was fixed 3 years ago but if you’re on ‘23, maybe relevant to you)

Hi @MarcCheong
Thanks for your response and for the additional info. My Pega version is INFINITY-25.1.1. I appreciate your guidance and will consider raising an incident if needed.

Thanks again for your help!

Best regards,
Eranda

Hi @JayachandraSiddipeta @MarcCheong

One thought I have is that this random/inconsistent behavior might be due to network or server response delays. Since the collapse action might rely on a client-server interaction, if there’s a slight delay, the UI may not register the collapse event immediately, causing the first drop-down to stay open occasionally.

I’m not 100% sure, but it might really be the reason this issue occurs, given the randomness of the behavior.
