How can i display Expand/Collapse +/- option in Row Headers of custom visual?

[xingchong]

This is a matrix custom visual, so how can i click this line, then drilldown this item?

Or can i display Expand/Collapse +/- option in this line? And what is the drilldown js function?

In format option of matrix visual, you have an option for +/- icon.

Hi @xingchong 

which the custom visual in using? Mostly, if you can't find the related setting in the format panel, it's not able to achieve this currently.

regretful, i am using the matrix visual, i wrote the custom visual myself, and i am a frontend developer.

i just want to collapse the line, then to show the next level.
