rootIsVisible not working

[thiensk]

Hello,

when i set property rootIsVisible of Ng2TreeSettings to false, the root tree node is still displayed. The other properties (showCheckboxes, enableCheckboxes) work correctly.

@thiensk Could you reproduce this using https://stackblitz.com?

Hello @rychkog ,

https://stackblitz.com/edit/angular-e3ex9j

the rootIsVisible is set to false, so i would expect the Programming Languages is not displayed and the first level nodes will be Object Oriented programming and Prototype Based programming

Thanks.

@thiensk @rychkog I saw the same thing. I suspect it is because you are missing the css styles, just as I was. The root is not visible because of CSS:

ng2-tree/src/styles.css

Lines 170 to 176 in b1124cb

	tree-internal ul.rootless {
	padding: 0;
	}
	tree-internal div.rootless {
	display: none !important;
	}
