Hello
What is your issue?

user findItem api
every item is situated
It’s incorrect!

When using findItem api,
every tree node is situated!
It’s incorrect!

input “… …”, and click find button,
“Mystrey&Thrillers” is situated and selected!
click find next button,
next item is situated and selected!

It occurs because of the accounting of regular expressions. The tree perceives a point as any symbol and find just the next item. You can change it as follows: find in your dhtmlxtree.js file _findNodeByLabe definition and replace 3th string with
searchStr = new RegExp(searchStr.replace(/([.?*+\[]()]{1})/gi,"\$1").replace(/ /gi,".*"),“gi”);
