Select ALL Option in Multiselect Dropdown

User Experience

Hi Team,

I have a requirement where we need to display a select all option in the multiselect dropdown so that the users can select all the values in one click.

Please help me with this.

Hi,

From my understanding, Pega does not provide an OOTB “Select All” option in a multiselect dropdown, and the approach depends on whether you’re using Theme Cosmos or Constellation.

  • In Theme Cosmos, you can achieve this using a custom control/section or additional logic

  • In Constellation, UI customization is limited, so adding “Select All” inside the dropdown is not supported

What you can try:

  • Add a separate “Select All” checkbox and use a data transform to populate all values

  • Use defaulting logic to prepopulate values if needed

In my opinion, this is usually handled through data transform/logic rather than UI customization.

Selecting all comes OOTB if you switch to a table layout.

my thoughts too. The business outcome is the ability to select all, so go with the interaction patterns provided that allow this.

Failing that, @PoojaPalla’s suggestion, I have seen implemented a few times - a manually added select all box or option in the list.

That said, I have also raised this as feedback, so it’s captured for future prioritisation (FDBK-141630)
