This logic was working before, by the way on clicking on of the icon on yaxis label everything working fine.
but when I'm clicking on the yaxis label it does not changing their class expand to collapse or we can say it does not running togglecollapse.

See: https://api.highcharts.com/gantt/chart.scrollablePlotArea.minHeight Demo: https://jsfiddle.net/BlackLabel/do4ywkrp/ Simplified demo: https://jsfiddle.net/Black...

Hi, I've seen the video, but it's not enough to tell what is the source of this problem. Seeing how it's implemented would let me know if it's a bug or an implementation issue. And if it's a bug, I need to find the cause of it. Kind regards! I have added a JSFiddle link please have a look. https://...

Hi, Thanks for contacting us! As for the first question, could you make a demo showing the problem in e.g. jsfiddle? It would be very helpful in finding the source of the error.

I think I got the solution, I am not getting tooltip because I have set outside = true in tooltip, but there is also and issue when I set outside = false then the tooltip becomes transparent.
