Something changed about the multiple dataset selection control. I used to be able to filter for a string like "_1" or "_2" and then easily select all the results. Now I have to manually click each item in the filtered list to select it. Is there a way to get the old behavior?
Thanks for reporting the change in the user interface behavior.
I can confirm that the filtering functionality is no longer present for multi-select. I tested in a 17_01 local Galaxy and it was not present there either, nor is it available in 17_05. This filtering feature was addressed in a much earlier release (see the ticket below for that change, it is linked in). When exactly the functionality was lost is not clear but we agree it would be nice to have it back!
I am using a MAC, so that might be a factor, however, it seems more likely that a Galaxy version prior to 17_01 is where you were able to filter with multi-select before.
I opened a ticket for the development team to review and consider adding it back in. Please see the details here, where you can also follow updates: https://github.com/galaxyproject/galaxy/issues/4215
The workaround is to use a Dataset collection instead of multi-select. This is how: https://galaxyproject.org/tutorials/collections/
Thanks again! Jen, Galaxy team
