Using angular 5, I need to draw a horizontal tree.
where I have to implement those line which should have dynamic as every box could have expanded.
So far I have implemented those boxes but no idea how to draw those line which will bind to the boxes whenever they expanded.
I was trying to do with d3js. but as I am new in d3 I would be glad if you could give me an idea which function or method would be appropriate for that kind of line
You can use primeng horizontal tree, which gives you same structure which you have drawn. The link is https://www.primefaces.org/primeng/#/tree. The another library i found is ngx-graph. Please use the following link. https://swimlane.github.io/ngx-graph/
