Holoview networkgraph selecting all connections to a specific node

Is there a way to plot only specific connections of a graph, connecting specific “node” to others , i.e. only showing a nodes and edges connecting to a specific “node”? (In examples of the website, I have seen that one can group nodes apriori and sub select the graph based on apriori defined labels.).
What I a wondering is, if it could be possible to:
1- give index of a node as input to hv.select()??
2- is it possible to output and save the result of the interactive mode, where one clicks on a node and sees its connections, as a separate graph?
