Collapse bars and resize GANTT diagram about gantt HOT 8 OPEN

Hello,
I started working on this feature because for a gantt view, it's fundamental, it seems and "frappe-gantt" is really interesting according to use.
Otherwise, just with css ... I don't know to do that and I wonder if it's possible or easy indeed when most of the objects are nested from svg... but it would be perfect, of course!

Short answer, I use d3.js to create depths in the groups of bars according to the tasks but each one implement this with its own method because it's not so simple anyway
For now I am still at the experimental stage with frappe-gantt ;)
It then allows to hide or show groups of dependent bars as seen on the gif ...
Still a lot to do anyway for me ;)

Hello ! Sorry for the delay...
Although still open, this issue is old and frappe-gantt has also evolved a lot since...

UPDATED
Anyway, I tried to review this without adding other libraries but without being able to open a PR, unfortunately.
Problem: dragging is only available after expanded the bars (only in this case).

Despite, it could be interesting to work by adding a "display" property to each task... for example and among others.
Of course, this is to be adapted according to your needs and is probably perfectible but if it can help someone.

I don't think this is easily doable using CSS. We might have to do this as a feature.

@jgorene If you have a working version, why not open a PR?

@netchampfaris Of course, it would be nice!
Unfortunately, I still use github on minimal features and I should make an effort for that;)
In addition, I worked around your very interesting library 2 months ago already, I'm on other things in this moment. In fact, I could not progress anymore to try to get what I wanted ... too complex for me. I would look at it later probably.

@jgorene please open PR

@jgorene Are you still working on it or have some workable solution.
Please suggest how i can integrate D3 with frappe-gantt to have expand collapse feature. It would be very helpful if you share your thoughts.
