Is it somehow possible to have chained pick lists, so that the selection in one pick list filters the options in the second one and the one thereafter?
Would you mind elaborating a bit on your question, I am having a hard time following. This page covers adding an item to a picklist that already exists in Specify (the picklist is for text1 in table CollectionObject, starts with values [‘Red’, ‘Green’, ‘Blue’] and has the value “Purple” added to it, resulting in [‘Red’, ‘Green’, ‘Blue’, ‘Purple’] after the operation).
Is there a particular picklist that you are interested in adding a value to?
I’m trying to add an item to the prepType picklist which already exists within Specify. There used to be a way in Specify 7 where you could see all existing picklists and add or delete items and was wondering if there was a similar way to see all picklists in Specify 7.
Ah I see! There are two pages about editing the prepType picklist (perhaps this highlights a need to reconcile or otherwise explain the difference between the two pages, I am not sure myself what the difference is)
If neither of these answer your question please let me know and can help further! You can always try out the edit/addition on sp7demofish to see how things work!
