Data type String lists, Sorting Edges, Node Label display

Hi all, I am trying to visualize a network between individuals based on common keywords.

1) Each individual has a list of string keywords. Using a list of strings as a node attribute, is there a way to partition the network and filter nodes based on strings in the string list? It seems that string lists are not recognized as string lists but strings.

Search 1st Degree as a column of string lists.

String lists treated as string

2) If I partition by edge labels, it is sorted by value counts in descending order. Is it possible to sort the values alphabetically?

3) Is it possible to view more selected node labels only after pointing at a selected node?
