Are there any recent solutions out there for end-users to manually order the dimension values from the server?
I have a workbook where end users want the ability to order the values in the column field. These are
string values so Tableau orders them alphabetically, but the user may want to see the order differently.
Of course you can manually sort the order of the values from the desktop version, but you can't once it's published
to server (unless I'm missing something).
On Server, sorting is available via tooltips, as well as from quick-sort buttons on quantitative axes. But you are correct that you can not grab-and-drag headers to manually sort.
There might be some parameter-and-calculation based tricks you could play to set up a few special predefined sorts for your users to choose between.
