Hello,when I have install this plugin,and I have setup as below,but it seem have't any change,



ask how so?Thank you!

upgrade it plz

Hi,

I don't know if I'm missing something (configuration and/or other plugins) but I cannot expand the first subtask using the arrow button (since there's no arrow button). Using "Expand/Collapse all" buttons works perfectly though. I think it considers that first row to be a "header row" as shown on the Redmine website (http://www.redmine.org/plugins/redmine_subtask_list_accordion). The problem is that I don't have that "header row" as you can see in the attached image below.

Thanks for your help.

@GEROMAX ,

Hi, i join the french translation for the version 1.1.0.
@+
fr.zip

I have installed the plugin in Redmine 4.0.1 and it works perfectly to expand or collapse all of them, but in the issues list I don't see the arrows to expand or collapse one by one as shown in the image.
I also have it installed in Redmine 3.3.0 and there it works correctly.
I have checked the html and I have seen that in Redmine 4.0.1 the parent tasks don't have the haschild class and they don't have the either.

Any idea how to fix it?
