How can we disable highlighting in the tree when an item is clicked?
You can’t block “selection-on-click” behavior, but you can made it invisible - just update css class of selected item in necessary way
dhtmlxtree.css
.selectedTreeRow{ background-color : navy; color:white; font-family : Verdana, Geneva, Arial, Helvetica, sans-serif; font-size : 12px; -moz-user-select: none; }
