java - FluentWait for dynamically created ListBox -

i have listbox(droplist) item created dynamically when click on div/span element .. however, when try click on listbox element after doing fluent wait , throws me error saying

element not clickable @ point (741, 192). other element receive click:"

if try use thread.sleep(2000) code runs perfectly. ideas on how can fix issue , make work in fluentwait. have tried elementtobeclickable,elementselectionstatetobe,presenceofelementlocated methods in expectedconditions class , throw same error. using chromedriver testing purposes .

my code , html snippet of page below

webelement elt = driver.findelement(by.xpath("//*[@id='grouptt']/span[2]/span/span[1]")); //clicking on span listbox activiated  actions act = new actions(driver); act.movetoelement(elt).click().build().perform();        fwait.until(expectedconditions.elementtobeclickable(driver.findelement(by.xpath("//ul[@id='group_listbox']/li[2]")))); //thread.sleep(2000) works fine here. driver.findelement(by.xpath("//ul[@id='group_listbox']/li[2]")).click(); 

html snippet

<div > <ul unselectable="on"  id="group_listbox"  role="listbox" style="overflow: auto; height: auto;"> <li tabindex="-1" role="option" unselectable="on" class="k-item" data-index="0"> group1 </li> <li tabindex="-1" role="option" unselectable="on" class="k-item k-state-selected k-state-focused" data-index="1"> group2 </li> <li tabindex="-1" role="option" unselectable="on" class="k-item k-state-selected k-state-focused" data-index="1"> group3 </li> </ul> </div> 

you can try change xpath locator find element inner text.

fwait.until(expectedconditions.elementtobeclickable(driver.findelement(by.xpath("//li[text() = 'group2']"))));
