ExtJS6: How to set leftpad margin to 0 for treelis

问题:

I have a treelist working using ExtJS6 but since items are left padded automatically given their depth and text inside it gets truncated for third child and deeper. Since I use it as a menu, having fixed width. I need to remove auto calculated leftpad margin. I did not find anything useful while going through extjs api for treelist. Could anyone please help

If you look at the code of treelist and treelistitem and abstract tree list item for a minute, you see that you can use the undocumented config property indent:0 or the method setIndent(0).

Not sure why it's not documented, presumably they intend to change the naming in future versions.

I have tested that it's working by opening the dashboard example, expanding the "pages" subtree, and then putting the following line into browser console:

Ext.ComponentQuery.query("treelist")[0].setIndent(0);
