select2 dropdown with selenium - selenium

Question

I have a drop down in WordPress products page which is a select2 ajax enabled.
I have managed to show the options in the drop down using selenium.
But i am not able to select one of the options from the list.
I am able to get the element using the below code. But the element is not castable to Select nor clickable.
driver.findElement(By.cssSelector("[class='multiselect attribute_values wc-enhanced-select select2-hidden-accessible enhanced']"))
Any ideas how to select any option from it?
The HTML code for the drop down is
<tr>
<td class="attribute_name">
<label>Name:</label>
<strong>Brand</strong>
<input type="hidden" name="attribute_names[0]" value="pa_brand">
<input type="hidden" name="attribute_position[0]" class="attribute_position" value="0">
</td>
<td rowspan="3">
<label>Value(s):</label>
<select multiple="" data-placeholder="Select terms" class="multiselect attribute_values wc-enhanced-select select2-hidden-accessible enhanced" name="attribute_values[0][]" tabindex="-1" aria-hidden="true">
<option value="107">Adidas</option>
<option value="110">Gul Ahmed</option>
<option value="111">Khadi</option>
</select>
<span class="select2 select2-container select2-container--default select2-container--above select2-container--open" dir="ltr" style="width: auto;">
<span class="selection">
<span class="select2-selection select2-selection--multiple" aria-haspopup="true" aria-expanded="true" tabindex="-1" aria-owns="select2-attribute_values0-to-results" aria-activedescendant="select2-attribute_values0-to-result-d16b-111">
<ul class="select2-selection__rendered" aria-live="polite" aria-relevant="additions removals" aria-atomic="true">
<li class="select2-search select2-search--inline"><input class="select2-search__field" type="text" tabindex="0" autocomplete="off" autocorrect="off" autocapitalize="none" spellcheck="false" role="textbox" aria-autocomplete="list" placeholder="Select terms" style="width: 418.797px;" aria-owns="select2-attribute_values0-to-results" aria-activedescendant="select2-attribute_values0-to-result-d16b-111"></li>
</ul>
</span>
</span>
<span class="dropdown-wrapper" aria-hidden="true"></span>
</span>
<button class="button plus select_all_attributes">Select all</button>
<button class="button minus select_no_attributes">Select none</button>
<button class="button fr plus add_new_attribute">Add new</button>
</td>
</tr>

As per the HTML:
<select multiple="" data-placeholder="Select terms" class="multiselect attribute_values wc-enhanced-select select2-hidden-accessible enhanced" name="attribute_values[0][]" tabindex="-1" aria-hidden="true">
The WebElement is clearly a <select> node and to select one of the options from the html-select tag you need to induce WebDriverWait for the elementToBeClickable() and you can use either of the following locator strategies:
Using cssSelector and selectByVisibleText():
new Select(new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.cssSelector("select.multiselect.attribute_values.wc-enhanced-select.select2-hidden-accessible.enhanced[data-placeholder='Select terms']")))).selectByVisibleText("Adidas");
Using xpath and selectByValue():
new Select(new WebDriverWait(driver, Duration.ofSeconds(10)).until(ExpectedConditions.elementToBeClickable(By.xpath("//select[#class='multiselect attribute_values wc-enhanced-select select2-hidden-accessible enhanced' and #data-placeholder='Select terms']")))).selectByValue("110");
