Expand subnode via code

[Ruud]

Hi,

I try to use this tree list; i need to expand a complete parent-multiple children in the tree. So:

- child deep in the hierarchy is known to my code and can be found in the tree list

- via code, the complete tree needs to be expanded to expand the child itself and all its parents

The demos only seem to work programmatically expanding nodes which are already displayed, but in this case the child nodes can be hidden. Is there a way to do this? Thanks in advance!

Best regards,

Ruud

Hello Ruud,

You can find the child node by id via the DataSource get method. Then, loop through all its parents (getting them via the parentNode method) and set their expanded state to true (node.set("expanded", true)).

For a working sample, see this Dojo snippet.

Hi Alex,

Thanks! So easy lol.. I guess i was a bit confused by the code used for doing the treelist.select(), where you have to put in a jQuery selector. I assumed the expand command also would need jQuery selectors; never thought of the treelist datasource object to accomplish this.  Rtfm it is:(..
