I've received some designs for a Tree View component and I'm not exactly sure how to align my implementation with the designs. The designer has set guidelines that stop at the last item of each depth level, meaning the connecting lines don't extend all the way to the bottom of the Tree View.
Currently, I've set up each item to have a connecting element that links back to the main branch (the line from the parent). The parent item has a line that goes to the height of its child elements, which seemed to work well in my initial tests.
However, when I actually applied it, I realized I overlooked that the last item in the list might have children as well. This led to a situation where the line extends to the last item even though it shouldn't have a connector attached.
I'm thinking of going back to the designer for a simplification, but I'm also open to any suggestions on how to tackle this challenge without completely changing direction. Just to add, I'm working with some constraints; the component needs a semi-transparent background and the height must be accurate without absolutely positioning the last item. The only solution I can think of hinges on knowing how many items will be displayed at a given level as they change with expansion or collapse.

It sounds like you're on the right track with the connector setup! If the last item shouldn’t extend to the bottom, you might want to consider dynamically checking how many children each node has. You can create a condition that only applies the connecting line if there are children present. This way, when rendering the tree, the last item's visibility of a connector can be adjusted depending on its children.
Also, using CSS or JavaScript to manipulate the line visibility could help. If your framework supports it, you could set a property to determine if the line should be drawn based on the state of the item—like expanded or collapsed.
That's a clever idea! Implementing a condition based on child presence could simplify things a lot. Plus, it keeps your design aligned with the original intent. Good luck with your implementation!
