<select class="form-control" id="eventCustomerID" name="eventCustomer">
    <option value="64" name="64">demou22_6hhh</option>
</select>

this is my code in a twig file

<select class="form-control" id="eventCustomerID" name="eventCustomer">
    {% set tags = 64|demou22_6hhh|split('|',1) %}
        {% for x in tags %}
            <option value="{{ x }}" name="{{ x }}">{{ x }}</option>
        {% endfor %}
</select>

I am stuck with this can someone help me out with this issue.

>Solution :

To achieve your required output, you shouldn’t use a for loop, but access the elements directly.

<select class="form-control" id="eventCustomerID" name="eventCustomer">
    {% set tags = "64|demou22_6hhh"|split('|') %}
    <option value="{{ tags[0] }}">{{ tags[1] }}</option>
</select>

Note about the second argument you are passing to the filter split

Not sure why you are passing 1 as the second argument. By setting this parameter to 1, you are limiting the output to one element in the array. More information here.
