selectMode='multi' on only certain rows

[AnejVovcak]

Hi everyone!

I have a use case where I have selectMode='multi', but I want to hide the checkbox in the select column for certain rows. On select all, only the ones with checkboxes would be selected. Is that possible? If I understand correctly, multi_filtered does not support this functionality.

No, at the moment it is not possible.

I can imagine the following new setting:

rowSelectable: (row: Row) => boolean

similar to rowClassFunction. This function would produce a Boolean for each row, deciding whether the row is selectable.

Of course, the "select all" would need to only consider selectable rows.

I think it is a good idea - to prevent a performance nightmare - to require from that function that it is pure and cache the result in the row object and only invalidate the cache when the data of the row changes.

Although this feature request is ages old and there was no feedback on the proposal, I think we should finally give it a shot in v3.4.0.

That was a bit too ambitious. The problem is, that we are still carrying the technical debt, that the DataSource implements the selection logic.
That would need to be fixed, first, but this is a breaking change. So unfortunately the topic cannot be addressed before a new major release.
