@MisRob I've implemented using KCardGrid with the card's #select slot for selection controls and overall work is done but have few doubts regarding UI.
I've noticed a UI behavior difference from the original:

• Original: Checkboxes are siblings to the cards, so cards don't shift when entering/exiting selection mode
• KDS implementation: Checkboxes use KCard's #select slot, which causes cards to shift slightly when selection mode toggles
  is this how KCard's selection slot is designed to work??
  Should I:

1. Keep the current KCardGrid + #select slot approach (KDS standard pattern)
2. Use a custom layout with external checkboxes (matches original UI exactly, but doesn't use KCardGrid)
   The functionality works correctly in both cases - it's just about the visual layout behavior. Please let me know which approach you prefer

Hi @vtushar06, thanks! As mentioned elsewhere, I will get back to this work after I am back from vacation later in January.

As for your question - thanks for raising that. Please use the standard KDS pattern KCardGrid and #select slot. It's important to stay with the pattern because under the hood, it takes care of semantics and a11y. I will then have a look at it, and see if we need to adjust KDS.

Also, I noticed that you added a completely new page Studio.. - however in this task, we need to take a different approach from other pages with cards, because we cannot yet migrate the whole page. This will come later and would be far out of scope of work around cards. Would you please revisit the guidance left in #5526 and only replaced the referenced place with the new card in the current CatalogList?

[vtushar06]

Hi @MisRob, thank you for the feedback, I understand you'd like a more minimal approach for this PR.

I followed the pattern from the reference PRs (#5227, #5524, #5525), which all created new complete page components (StudioMyChannels, StudioStarredChannels, StudioViewOnlyChannels). Since the guidance in #5526 said to "replace" the section and "use KCardGrid", I created StudioCatalogList.vue as a complete KDS implementation.

If you prefer a hybrid approach instead, I will make changes accordingly.

[MisRob]

@vtushar06, this issue is a bit different from others for a number of reasons - I think you can just follow the issue's guidance and it should be fine.

[vtushar06]

Yeah @MisRob now I applied changes according to guidance, I got so much into other issue learning that's why I used similar approach.
and cards shift still exists please let me know about after your Holidays.
