Title: Combotree - how to prevent selection of group headings
Post by: Quarkrunner on November 03, 2013, 05:47:51 PM

I can't work out how to prevent users from selecting the group headings within a combotree. We want them to display so that they can be opened to reveal the children, but we need to prevent selection of the group headings themselves. Please advise.

The 'onBeforeSelect' event can be used to determine what nodes can be selected.

Code:

$('#cc').combotree({
  onBeforeSelect:function(node){
    if (...){return false)  // return false to prevent from selecting a node.
  }
});

Many thanks.

As a follow up, if instead we wanted to treat clicking the group heading the same as clicking the arrow (ie. opening and closing the group), how would that be done?
