[Ullas-A-2000]

suppose on node click or a html class code how do we determine that a card is a ancestor of root user or descendant of root user

This demo highlight the nodes to the root: https://code.balkan.app/family-tree-js/highlight-selected-node#JS

suppose yermolai kozolv is root user

his parents should be identified as ancestors and his children shold be identified as descendants

how?

Please explain in steps the behavior that you need? Click on which node? Then highlight or what and which nodes exactly?

lets say , my name is jhon and im the root user of tree

jhon has two children ema and may jhon has parents dexter and juliet

when i click on ema i should get descendant when i click on dexter i should get ancestor

similarly dexters parents are also jhons ancestors so when i click on them i should get ancestors and ema's childrens are also jhons descendants so when i click on the i should get descendants
