If a library has only one branch or the singleBranchMode preference is activated, don't show the library filter on the left side of the full serial issue history page. To test: - add a subscription to a serial - go to the OPAC detail page - subscription tab > more details link at the bottom - full history tab - library filter to the left always shows, independent from number of branches
The problem here is, that it's all Javascript. And the second field for the subscription id is only unlocked, if a library is chosen. A bit too confusing for me right now - maybe someone else wants to give this a try.
