Some dropdown is not implemented as html options.
How can we select 2 or 3 items in this case.
The dropdown Html is similar to the following

<div class="rc-virtual-list-holder-inner" style="display: flex; flex-direction: column;"><div label="Date(datetime)" aria-selected="false" class="ant-select-item ant-select-item-option" title="Date(datetime)"><div class="ant-select-item-option-content">Date(datetime)</div></div><div label="Open(numeric)" aria-selected="false" class="ant-select-item ant-select-item-option" title="Open(numeric)"><div class="ant-select-item-option-content">Open(numeric)</div></div><div label="High(numeric)" aria-selected="false" class="ant-select-item ant-select-item-option" title="High(numeric)"><div class="ant-select-item-option-content">High(numeric)</div></div><div label="Low(numeric)" aria-selected="false" class="ant-select-item ant-select-item-option" title="Low(numeric)"><div class="ant-select-item-option-content">Low(numeric)</div></div><div label="Close(numeric)" aria-selected="false" class="ant-select-item ant-select-item-option ant-select-item-option-active" title="Close(numeric)"><div class="ant-select-item-option-content">Close(numeric)</div></div><div label="Adj Close(numeric)" aria-selected="false" class="ant-select-item ant-select-item-option" title="Adj Close(numeric)"><div class="ant-select-item-option-content">Adj Close(numeric)</div></div><div label="Volume(numeric)" aria-selected="false" class="ant-select-item ant-select-item-option" title="Volume(numeric)"><div class="ant-select-item-option-content">Volume(numeric)</div></div></div>
