In the table view, we have a context menu item named show only selected items, since it says ‘segments’, I assume we should be able to select multiple segments at once, however, I found I can only select one segment once. But I have an amount of 50 segments, how can I select and show them at once? Thanks!

I have read the source code, it seems single selection is intended:

Can anyone explain why not support multiple rows selection, thanks!

You can go to Segmentations module for a segment list with multi-select enabled.

All the segment editor effects currently assume that there is only a single segment is selected. Simply enabling multiple selection would break them. Multi-select would be meaningful for some effects, with certain parameter settings, so it could be useful to implement this. We don’t have plans for implementing this, but contributions are welcome!
