https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=35383 --- Comment #5 from Slava Shishkin <slavashishkin@gmail.com> --- (In reply to Marcel de Rooy from comment #4) thanks, that makes a sense, I can wrap up it in "if", if (typeof Sortable !== 'undefined') { $(clone).find("ul.sortable_subfield").each((i, e) => { Sortable.create(e, { animation: 150, }); }); } but the best then is to make a callback option for CloneSubfield and leave Sortable.create code in files where it resides, but that also leads to refactoring of onclick="CloneSubfield... to modern way how we doing that in our codebase by moving that listener to JS document ready block Marcel, what do you think? -- You are receiving this mail because: You are watching all bug changes.
