th:selected for select tag in Thymeleaf not working

<select multiple="multiple>

<option th:each="vName : ${variety}"

th:value="${vName}"

th:text="${vName}"

th:selected="${selectedVariety}"></option> 

</select>

In the above code "selectedVariety" is a string array sent from controller.

I'm not able to bind the select tag on edit.

And this select tag is not a part of entity table so th:filed="*{selectedVariety}" is not working.

Tried th:attr="selected=${selectedVariety==vName?true:false}">

Not working

On using this "th:selected="${selectedVariety}" every option in the dropdown is getting selected.

What may be the solution??

The option is selected when the value is included to the String array. You'll need following attribute within your <option>:

th:selected="${#arrays.contains(selectedVariety, vName)}"

It returns true (selected) if selectedVariety contains given vName or false (unselected) otherwise.
